Sažetak
World Health Organization has recognized the problem of antimicrobial resistance as one of the most important issues in world health protection. Due to the increasing resistance of harmful bacteria and other microorganisms to conventional drugs, it is necessary to develop new solutions for medical textile materials. The antimicrobial properties of silver ions are intensively investigated in a form of silver ions and silver nanoparticles, so their application on medical textile materials is very important. Therefore, this study aimed to functionalize textile surfaces with antimicrobial microcapsules filled with antimicrobial substances. The characterization tests were performed by ultraviolet and visible spectrometry on samples containing silver in microcapsules in both nanoparticle and ionic forms. Testing of the samples was performed on ready-made microcapsules obtained from sodium alginate, which contained silver in their core. In contrast, the outer shell was made of zinc sulfate 7-hydrate. The encapsulation method using the Buchi Encapsulator B-390 encapsulator was used to obtain these microcapsules. For characterization purposes, the test was performed on a two-beam Lambda 20 instrument, manufactured by Perkin Elmer from the United States. The test was performed in the ultraviolet and visible range, in the range of 190 to 900 nm. The test was performed in an aqueous medium in which the microcapsules released silver. The obtained test results will enable the determination of the concentration of silver released over time from microcapsules in an aqueous medium, and based on the obtained results, the antimicrobial properties of silver ions will be estimated based on the released quantities that are efficient for removal of certain strains of microorganisms on textile medical materials.
