In this study, silver nanoparticles (AgNP) were synthesized using the biological method Hypericum triquetrifolium Turra. The synthesized silver nanoparticles (AgNP) were illuminated using spectroscopic methods such as Fourier transform infrared spectroscopy (FT-IR), Ultraviolet/visible light absorption spectrophotometer (UV-vis), X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy-dispersive X-ray (EDAX) and Thermogravimetric-Diferential thermal analysis (TGA-DTA). The antimicrobial activities of synthesized silver nanoparticles on microorganisms were investigated.
Çevre dostu sentez yöntemlerinin her geçen gün daha etkin olması ve nanopartiküllerin (NP'lerin) kullanım alanlarının yaygınlığı bu yöntemlere olan ilginin oldukça artmasına neden olmaktadır. Biz atık durumunda ki zeytin yapraklarından elde ettiğimiz özüt ile gümüş nano partikülleri (AgNP'leri) basit, ucuz ve çevre dostu bir yöntemle sentezledik. Bu partiküllerin Ultraviyole ve Görünür Işık Absorpsiyon Spektroskopi (UV-Vis.), Fourıer Dönüşümlü Kızılötesi Spektroskopisi (FTIR), X-Işınları Kırınım Cihazı (XRD), Taramalı Elektron Mikroskobu-Enerji Yayılımlı X-ışını (SEM-EDX) ve Termo Gravimetrik (TGA-DTA) analizleri kullanılarak karakterizasyon işlemi yapılmıştır. Antibiyotik dirençliliği günümüz dünyasının ciddi sorunlarından biri bu sebeple elde edilen partiküllerin patojen gram pozitif Staphylococcus aureus ATCC 29213, gram negatif Escherichia coli ATCC 25922 suşları ve Candida albicans mayası üzerinde etkili bir anti-mikrobiyal aktivite gösterdiği tespit edilmiştir. AgNP'lerin MİK (Minimum İnhibisyon Konsantarasyon) değerleri sırası 0.112, 0.028, ve 0.007 olarak bulunmuştur.
The consumption of plants and their use for medicinal purposes are increasing day by day. Therefore, knowing the plant contents is important for human health. In this study, metal contents of nineteen species belonging to four different families were determined. Different species belonging to the same genus belonging to these families and metal contents of different parts of the same sample were compared with each other. The metal contents of different species of the same genus have been determined that be different from each other. The metal contents of different parts of the same species were determined that be different from each other. In addition, the Cd and Pb metal content results of the species were compared with the maximum allowable concentration values in raw plant material of the World Health Organization's (WHO). Cd metal content in all species was found to be higher than the value determined by the WHO. Only the Pb metal content of the A3 species was found to be higher than the value determined by WHO.
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.
