Application of arti ficial intelligence in modeling of the doxorubicin release behavior of pH and temperature responsive poly(NIPAAm-co-AAc)-PEG IPN hydrogel
(Elsevier, 2020) Boztepe, Cihangir; Kunkul, Asim; Yuceer, Mehmet
Modeling of the drug release behavior of stimuli-responsive hydrogels is a domain of steadily increasing academic and industrial importance. It is very difficult to accurately predict the drug release kinetic of this type drug carrier materials due to environmental variables in the body such as pH and temperature. In this study, a pH- and temperature-responsive poly(N-Isopropyl acrylamide-co-Acrylic acid)/Poly(ethylene glycol) (poly(NIPAAm-co-AAc)/PEG) interpenetrating polymer network (IPN) hydrogel was synthesized by free radical solution polymerization in the presence of poly(NIPAAm-co-AAc) microgels and PEG. The synthesized IPN hydrogels showed rapid pH- and temperature-responsive deswelling behavior. The textural properties and surface morphology of poly(NIPAAm-co-AAc) IPN hydrogel were characterized by scanning electron microscopy (SEM) analysis technique. The doxorubicin (DOX) was loaded to the hydrogels by swelling the hydrogels in the DOX solution. The cumulative release of DOX has been investigated as a function of time, pH and temperature. Experimental DOX release data obtained were successfully modeled using ANNs, LS-SVM and SVR methodologies. To evaluate the performance of these models, four statistical parameters: correlation coefficient (R), root mean squared error (RMSE), mean square error (MSE) and mean absolute percentage error (MAPE) were calculated. It was found that the developed ANN model show best performance in modeling the DOX release behavior of poly(NIPAAm-co-AAc)/PEG IPN hydrogels.

(Elsevier, 2023) Oruc, Sedat; Boztepe, Cihangir; Zengin, Reyhan
Characterizing the effects of parameters such as the swelling ratio, composition, and applied current frequency of hydrogels is crucial for the development of flexible, stretchable, and electrically conductive hydrogels that are of importance in a variety of biomedical applications. In this study, poly(Acrylamide) (PAAm), alginate (Alg) and crystalline nanocellulose (CNC) based stretchable PAAm/Alg/CNC/rGO hydrogels containing different amounts of reduced graphene oxide (rGO) in their structure were synthesized. To increase the electrical conductivity of these hydrogels, their composites with polyaniline (PANI) were prepared. The chemical composition and morphological characterizations were performed using FT-IR and SEM analysis techniques. Since the amount of PANI formed in the structure of hydrogel composites was directly proportional to the amount of rGO in the structure, swelling, mechanical and electrical conductivity properties changed depending on the amount of rGO. The swelling ratio and mechanical strength of the PAAm/Alg/CNC/rGO/PANI hydrogel composite series varied between 38 and 50 g water/ g polymer and 76.02-375.95 kPa, respectively. The electrical conductivities of their 25% swollen states at 10-4 MHz ranged from 15.4 to 20.20 S/m. Flex sensor, smart hydrogel fingers and electrocardiogram (ECG) electrode applications were tested. The synthesized hydrogel composite systems were quite successful in these biomedical applications as bioelectronic materials.

(Elsevier Science Sa, 2018) Boztepe, Cihangir; Kunkul, Asim; Yasar, Sedat; Gurbuz, Nevin
New generation, novel, environmentally safe polymeric heterogeneous catalysts which included catalytically active NHC-Pd-pyridine complexes were prepared by radical polymerization of NHC-Pd-pyridine complexes with Acrylamide (AAm) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) monomers in the presence of N,N'-methylenebisacrylamide (MBA) crosslinker. Structural characterization of NHCPd-pyridine complexes was conducted by using NMR, FT-IR while the structural characterization of crosslinked polymeric catalyst systems was made by using FT-IR, SEM, SEM-EDX, TEM and TGA analysis techniques. The synthesized polymer-based NHC-Pd-pyridine catalysts showed good catalytic activity for Suzuki reaction of aryl bromides with phenylboronic acid in aqueous media. They exhibited good stability and they could be reused at least five times without remarkable loss of catalytic activity. (C) 2018 Elsevier B.V. All rights reserved.

(Elsevier, 2020) Boztepe, Cihangir; Kunkul, Asim; Gurbuz, Nevin
Increasing environmental awareness and limited raw material resources have increased the importance of catalysts by leading to green technology. For this purpose, there is a need for efficient, new, selective, reusable, environmentally friendly catalysts and catalytic systems. In this study, PEPPSI (pyridine enhanced precatalyst preparation, stabilization, and initiation) type and vinylimidazole (VI) based palladium complexes of N-heterocyclic carbenes (PEPPSI-Pd-NHCs) which have catalytic activity in homogeneous Suzuki and Heck reactions were prepared. To obtain environmentally safe polymeric heterogeneous catalysts, this novel PEPPSI-Pd-NHC complexes were polymerized with Acrylamide (AAm) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) by free radical polymerization. Characterization of PEPPSI-Pd-NHC complexes and polymer supported catalysts were made by using various elemental and structural analyses techniques. The synthesized polymeric supported heterogeneous catalysts have high activity, stability and reusability for Suzuki and Heck reaction of aryl bromides in aqueous media. (C) 2020 Elsevier B.V.

(Wiley, 2019) Boztepe, Cihangir; Kunkul, Asim; Gurbuz, Nevin; Ozdemir, Ismail
One of the most important challenges of the Suzuki reaction is a green synthesis of reaction products. In terms of economy and ecology, the Suzuki reaction details must be characterized for the industrial-scale Suzuki reaction processes. In this paper, for the first time, a kinetic and mechanistic study on the Suzuki reaction catalyzed with hydrogel-supported PEPPSI (pyridine-enhanced precatalyst preparation stabilization (and) initiation) type NHC-Pd-pyridine composite has been investigated. To determine the rate-limiting step, the effects of reactants and experimental conditions on the heterogeneous Suzuki reaction have been experimentally defined. The experimental results demonstrated that it is possible to reach 100% yield under the optimum reaction conditions, which were found as 75 x 10(-3) mol/L of phenylboronic acid (FBA), 50 x 10(-3) mol/L of bromoacetophenone (Brac), 125 x 10(-3) mol/L of K2CO3, 1 g/L of catalyst, 80 degrees C of reaction temperature, 400 rpm of mixing rate, and 3 h of reaction time. The transmetalation step in the cycle was defined as the rate-limiting step. On the basis of kinetic results, a mathematical reaction rate expression was presented assuming the steady-state approach to steps of the catalytic cycle. The activation energy (E-a) of the reaction was estimated to be 34.88 kJ/mol.

(Taylor & Francis Inc, 2015) Boztepe, Cihangir; Solener, Musa; Yuceer, Mehmet; Kunkul, Asim; Kabasakal, Osman S.
Hydrogels based on acrylamide (AAm) were synthesized by free radical polymerization in an aqueous solution using N, N'-methylenebisacrylamide (MBAAm) as crosslinker. To obtain anionic hydrogels, 2-acrylamido-2-methylpropanesulfonic acid sodium salt (AMPS) and acrylic acid (AAc) were used as comonomers. The swelling behaviors of all hydrogel systems were modeled using an artificial neural network (ANN) and compared with a multivariable least squares regression (MLSR) model and phenomenal model. The predictions from the ANN model, which associated input parameters, including the amounts of crosslinker (MBA) and comonomer, and swelling values with time, produce results that show excellent correlation with experimental data. The parameters of swelling kinetics and water diffusion mechanisms of the hydrogels were calculated using the obtained experimental data. Model analysis indicated that the ANN models could accurately describe complex swelling behaviors of highly swellable hydrogels.

(Elsevier, 2022) Balan, Kaan Emre; Boztepe, Cihangir; Kuenkuel, Asim
There is a growing demand to design and development of hydrogel based stimuli responsive drug-delivery systems due to possess several advantages, namely high drug loading capacity, target specific delivery, biocompatibility, reduced drug toxicity and controlled drug release. Because their drug release behavior is dependent on many factors, it is very difficult to accurately characterize these behaviors. So, the characterization of drug loading and release behaviors is very important from an industrial and academic point of view. In this study, pH and temperature responsive poly(NIPAAm-co-VSA)/Alginate interpenetrating polymer network (IPN) hydrogel was synthesized by free radical polymerization in the presence of Poly(NIPA-co-VSA) nano gels. Na-Alginate natural polymer was used to physically cross-link the hydrogels with the Ca(2+ )ions. To obtain physically crosslinked hydrogel series at different rates, hydrogels were kept in various concentrations of CaCl2 solutions. The mechanical, chemical and morphological properties of obtained hydrogel series were characterized by compression test, FT-IR and SEM analysis techniques. As a result of the mechanical tests, it was determined that the fracture strengths varied between 137 and 830 kPa. The doxorubicin (DOX) loading capacities of the hydrogels were determined to be between 86 and 161 mg DOX/g polymer by the solution impregnation method. Their DOX release behavior have been investigated as a function of time, pH, temperature and physical cross -linking degree of hydrogel. Experimentally obtained and highly complex DOX release behaviors were success-fully modeled with the artificial neural network (ANN) technique.

N-heterosiklik karbenler (NHC) son yıllarda organometalik kimyada genis bir arastırma konusu olarak çalısılmaktadır. NHC-Metal kompleksleri güçlü ?-dönör, düsük ?-akseptör özellikleri sayesinde yüksek sıcaklıga, havaya ve neme karsı kararlıdır ve birçok reaksiyonda katalizör olarak basarıyla kullanılmaktadır. Bu kompleksler genellikle homojen katalizörlerdir ve tepkime ortamından ayrılmaları zordur. Bu katalizörlerin heterojen hale getirilerek tekrar kullanılmaları ekonomik ve ekolojik açıdan çok önemlidir. Bu nedenle sentezlenen katalizörlerin tekrar kullanılabilir olmasının yanında, çaprazbaglı polimerik destek maddesine tutturulmus özgün ve yüksek aktiviteye sahip karben komplekslerinin gelistirilmesi bilimsel açıdan çok önemlidir ve literatürde bu alandaki boslugu doldurmustur.

(Springer, 2020) Boztepe, Cihangir; Yuceer, Mehmet; Kunkul, Asim; Solener, Musa; Kabasakal, Osman S.
One of the most important fields of interest in respect of stimuli-responsive hydrogels is modeling and simulation of their deswelling behavior. The problem mentioned above plays an important role regarding diffusion of fluid from hydrogel to media, what is very useful in biomedical applications, such as controlled drug delivery systems, biomaterials or biosensors. In this study, the pH- and temperature-responsive poly(N-isopropylacrylamide-co-acrylic acid) interpenetrating polymer network (poly(NIPAAm-co-AAc) IPN) hydrogel was synthesized by free radical solution polymerization method. In order to improve the deswelling rate of the conventional poly(NIPAAm-co-AAc) hydrogels, their IPN structure was synthesized by using poly(NIPAAm-co-AAc) microgels. The chemical structure and surface morphology of poly(NIPAAm-co-AAc) IPN hydrogels were characterized by FT-IR and SEM analysis techniques. The synthesized poly(NIPAAm-co-AAc) IPN hydrogel has high swelling capacity (112 g water/g dry polymer at 20 degrees C and pH 7) and exhibited fast and multivariable deswelling behaviors dependent on pH and temperature. The pH- and temperature-dependent mechanical property of IPN hydrogel was investigated. It was found that the compressive strength of the IPN hydrogels was changed inversely proportional to the swelling capacity. To develop the model for deswelling behaviors of IPN hydrogel, artificial neural network (ANN) model and least squares support vector machine model techniques were used. The predictions from the ANN model showed very good correlation with observed data. The results indicated that the ANN model could accurately predict complex deswelling behavior of pH- and temperature-responsive IPN hydrogels.

(Wiley, 2021) Boztepe, Cihangir; Daskin, Mahmut; Erdogan, Ahmet; Sarici, Talha
It is very important that new generation, unique, high mechanical strength, and biocompatible hydrogel composites are developed due to their potential to be used as biomaterials in the biomedical field. Modeling of the swelling capacity and mechanical strength behavior of hydrogels is a domain of steadily increasing academic and industrial importance. These behaviors are difficult to model accurately due to hydrogels show very complex behavior depending on the content. In this study, a series of poly(acrylamide-co-2-acrylamido-2-methylpropan sulfonic acid)-g-carboxymethyl cellulose/TiO2 (poly(AAm-co-AMPS)-g-CMC/TiO2) superabsorbent hydrogel composites were prepared by free-radical graft copolymerization in aqueous solution. Structural and surface morphology characterizations were conducted by using Fourier-transform infrared spectroscopy and scanning electron microscope analysis techniques. For modeling the equilibrium swelling capacity and fracture strength behaviors of hydrogels, the composition parameters (such as mole ratio of AMPS/AAm, wt% of CMC, and wt% of TiO2) was proposed by response surface method (RSM) Design Expert-10 software. Statistical parameters showed that the RSM model has good performance in modeling the swelling capacity and mechanic fracture strength behaviors of poly(AAm-co-AMPS)-g-CMC/TiO2 hydrogel composites. According to the RSM model results, the maximum swelling capacity and fracture strength values were calculated as 270.39 g water/g polymer and 159.23 kPa, respectively.

(Taylor & Francis As, 2017) Boztepe, Cihangir; Tosun, Emir; Bilenler, Tugca; Sislioglu, Kubra
A series of acrylamide (AAm)-based hydrogels containing acrylic acid, 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), and vinyl imidazole (VI) comonomers were prepared by free radical polymerization. Silver nanoparticles were loaded to hydrogel systems through in situ reduction of silver nitrate in the presence of sodium borohydride as a reducing agent. The synthesized hydrogels and their composites were characterized using FTIR, scanning electron microscopy, EDX, and EDX-mapping. The antimicrobial activity of hydrogel-silver composite was determined using well agar and broth dilution tests. In the first stage, four different hydrogel-silver composites were evaluated against six different microorganisms using the well agar technique. The most effective hydrogel-silver composite among all tested was poly(AAm-co-VI-co-AMPS)-Ag, while the most sensitive and resistant microorganisms among all tested were Staphylococcus cerevisiae and S. aureus, respectively. Poly(AAm-co-VI-co-AMPS)-Ag composite was used in modeling the inhibition kinetic of Escherichia coli. The present study displays that hydrogel-silver composite has considerable antimicrobial activity, which deserves further investigation for use in clinic application and industrial processing.

(Wiley, 2023) Boztepe, Cihangir; Vanli, Tugce
The development of magnetic field-sensitive smart drug delivery systems with superior properties has become an area of increasing academic and industrial importance. In this study, smart poly(NIPAAm-co-VSA)-rGO/Fe3O4 ferrogels with varying concentrations of reduced graphene oxide (rGO) were synthesized. Fe3O4 nanoparticles loaded ferrogels were obtained by the in situ reduction of Fe ions. The morphologic, structural, and magnetic properties of ferrogel systems were characterized. Doxorubicin (DOX) was loaded to the synthesized ferrogels by solution impregnation method and their heating and drug release behavior over time under alternating magnetic field AMFs of 1.37, 1.64, and 1.91 millitesla (mT) were investigated. The drug loading and releasing characteristics of the ferrogel series were calculated. When the experimental results were examined, it was determined that the amount of rGO in the structure of the developed ferrogel systems had a very high effect on the magnetic, heating, and drug loading-release characteristics of the ferrogels. To modeling their multivariable DOX release behavior, artificial neural network modeling technique was used. Calculated model performance parameters have shown that this developed artificial intelligence technique has great success in modeling complex and nonlinear DOX release behaviors.

(Elsevier, 2022) Boztepe, Cihangir; Daskin, Mahmut; Erdogan, Ahmet
Synthesis of stimuli-responsive hydrogels and modeling their behaviors under stimulus are very important for the use of smart materials in biomedical applications. In the present study, magnetic field responsive and novel poly (N-Isopropylacrylamide-co-Vinylsulfonic acid)/Fe3O4 interpenetrating polymer network (poly(NIPAAm-coVSA)/Fe3O4 IPN) hydrogel composite (ferrogel) series were successfully synthesized. Firstly, temperature responsive poly(NIPAAm-co-VSA) IPN hydrogels containing various amount of vinylsulfonic acid (VSA) were synthesized by two polymerization method: emulsion and solution polymerization. Then, Fe3O4 nanoparticles were loaded to hydrogel systems through in situ reduction of Fe2+/Fe3+ ions. Their chemical structures, magnetic properties and surface morphologies were characterized by FT-IR, VSM and SEM analysis techniques. The effects of the VSA content in ferrogel composition on deswelling and heating behavior of ferrogels under various of alternating magnetic fields (AMFs) were experimentally investigated. In order to characterize their heating and deswelling behaviors by magnetic induction heating, heating and deswelling kinetics under 1.37, 1.64 and 1.91 mT magnetic fields were investigated. Their fully swollen states showed complex deswelling and heating behaviors. Artificial neural networks (ANNs) in MATLAB were used to model these behaviors. The ANN models which associated input variables, were able to accurately predict complex deswelling and heating behaviors of magnetic field-responsive poly(NIPAAm-co-VSA)/(FeO4)-O-3 IPN hydrogel composites.
