When the patient has pleurodesis, the pleural fluid is drained first and then talc is applied to the pleural space. The talc application process consists of directly depositing the talc structure with the appropriate particle size into the relevant space. Both the space is filled and the patient's lung movement comfort is provided during the breathing process due to the slippery effect of the talc structure. Otherwise, the patient experiences a very painful process during the breathing process. However, some important indications can be observed both during and after the talc deposition. At the beginning of these indications is the formation of infection and innovative practices are very significant in eliminating such an infection. In order to prevent infection during talc process, intensive antibiotic application is made before and after the application. In this study, more effective and innovative talc structures were developed and the talc structure was modified with a zwitter ionic polymeric coating to prevent infection. A surface modification was carried out by attaching 3-vinylpropyl-triethoxysilane binding agent on the appropriately sized talc structures. The functionalized talc structure was transformed into a surface that would work with the kill and release principle. The structure of 2-(tert-butylamino)ethyl methacrylate was modified for this process. A quaternary ammonium structure was formed on the talc surface thereby, bacteria will be killed and then, removed from the surface. In the research, local anesthesic agent lidocaine was also loaded to provide convenience to the patient. Structural characterizations of the obtained structures were performed by Fourier Transform Infrared Spectrophotometer (FTIR). Its thermal properties were determined by thermogravimetric analysis (TGA), differential thermal analysis (DTA) and differential scanning calorimetry (DSC) techniques. Moreover, the antibacterial properties of the obtained structures were examined.eninfo:eu-repo/semantics/closedAccessPleural talcSurface modificationAntibacterial surfacesKill and release systemLidocaineArticle83110.1007/s00289-025-06063-02-s2.0-105023500779Q1WOS:001631051300004Q20000-0001-6080-229X0000-0001-9018-78490000-0001-9497-34680000-0002-4085-02240000-0001-6783-70300000-0002-4788-278X
