Bu çalışmada çok gözenekli (MSN) ve tek gözenekli (HSS) silika nanopartiküllerin yüzeyinde, viniltriazol (VTri) monomerinin polimerizasyon reaksiyonu ile amin grupları oluşturulmuştur. Hazırlanan nanokompozit yapıların karakterizasyonu ve antifungal özelliği incelenmiştir. Nanokompozitlerin karakterizasyonunda MSN ve HSS' nın viniltriazol ile etkileşimini, yüzeydeki azol gruplarının varlığını belirlemek için FTIR ve XRD analizi, termal özelliklerini incelemek için TGA analizi yapılmıştır. Nanokompozitlerin morfolojisini belirlemek için SEM analizi yapılmıştır. Nanokompozit yapıların antifungal özellikleri MİK yöntemi ile kanıtlanmıştır.
This research aims to improve antimicrobial materials based on functional silica nanoparticles. Three different methods were used in the study to create silica nanoparticles with other properties. The nanoparticles' morphological structures are porous, hollow, and filled with spherical forms. The surface of these nanoparticles was grafted with poly(1-vinyl-1,2,4-triazole) (PVTri). The morphological properties of nanocomposites were used for analyze. In contrast, thermal gravimetric analysis was used to characterize the thermal properties of nanocomposites (TGA). The silica nanoparticles were evaluated for them in vitro antimicrobial activity against, Escherichia coli, Staphylococcus aureus, Saccharomyces cerevisiae using minimum inhibitory concentration (MIC) measurement. Silica nanoparticles have different antifungal and antibacterial properties related to their structure. The cytotoxic effects of the silica nanoparticles on HaCaT cells were performed with an MTS assay. In this study, we observed that high doses of HSS and e-SiO2 decreased cell growth, while HSS and e-SiO2 composite with PVTri increased cell proliferation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
