Cobalt nanoparticle production using algal extract A nanocarrier for antimicrobial potential

초록

The present study aimed to characterize CoNPs that were synthesized using a simple, inexpensive, and eco-friendly way from algal-extract of Elodea canadensis. Further, this study also assessed the antimicrobial potential of the synthesized CoNPs. The CoNPs formation was preliminarily proved through colour change from light-pink to brown within 15 min upon adding the algal-extract to the cobalt (II) nitrate solution. The I 203 8.109 20 On: Sun 18 Jun 2023 1028:05 maximum absorption peaks at 450nm for the algae-encapsulated CoNPs were obtained using UV-Vis spec -Copyright: American Scientific Publishers trum. FTIR result proved that CoNPs were cappd with active components from E. canadensis as distinct Delivered by Ingenta peaks were observed at 3288.4 and 1641.8 cm(-1) in the infrared spectra of the algal-extract and bio-reduced CoNPs. A FE-SEM revealed that CoNPs were agglomerated and had smooth surfaces. In addition, FE-TEM indicated that the synthesized CoNPs had assorted sizes and shapes. Meanwhile, the XRD displayed several broad peaks at 20 = 52.37 degrees, 54.21 degrees, and 56.09 degrees with mean size of 14.022 nm that affirmed the crystalline nature of algal synthesized CoNPs. The antimicrobial potential of the biosynthesized CoNPs was assessed using the disc-diffusion test.
