Screening of microalgae for biosynthesis and optimization of Ag/AgCl nano hybrids having antibacterial effect

Abstract

Here we report a facile and novel bio-synthesis technique, using algal extract to reduce silver metal ions into Ag/AgCl nanoparticles.

Biosynthesis and Characterization of Silver Nanoparticles produced by Phormidium ambiguum and Desertifilum tharense

“…6A and 6B). It was known that Ag-NPs give the plasmon resonance peak in absorption spectrum between 410 -450 nm (Kashyap et al, 2019). Consequently, the results confirmed successful extracellular Ag-NPs synthesis by Desertifilum tharense and Phormidium ambiguum under light conditions.…”

“…The average size of Ag-NPs from Chlorella sp. was 90.6 nm (Kashyap et al, 2019). Some cyanobacterial cultures synthesized silver particles with a size larger than 100 nm.…”

“…Some cyanobacterial cultures synthesized silver particles with a size larger than 100 nm. Keskin et al (2016) and Kashyap et al (2019) produced particles with average size of 140 nm from Synechococcus sp., and size of 136.2 and 241.8 nm from Scenedesmus vacuolatus and Lyngbya putealis, respectively.…”

“…Therefore, the biosynthesis of nanoparticles using different biological sources including plants, bacteria, fungi and algae has great attention. The biological methods are cost effective, non-toxic, pollutant-free and eco-friendly methods (Malhotra et al, 2013, Keskin et al, 2016, Kumar et al, 2018and Kashyap et al, 2019.…”

Structurally and Compositionally Tunable Absorption Properties of AgCl@AgAu Nanocatalysts for Plasmonic Photocatalytic Degradation of Environmental Pollutants

“…In addition to pure AgCl, composite nanostructures composed of AgCl and noble metals have recently been synthesized [5,6,[11][12][13]. However, most of the composite nanostructures were still compositionally limited to Ag/AgCl, whose sizes and shapes, and corresponding chemical and physical properties, were hardly controlled [14][15][16][17]. These shortcomings mainly originated from the limited synthetic conditions of noble metal/AgCl composite nanostructures.…”
