Synthesis of greener silver nanoparticle-based chitosan nanocomposites and their potential antimicrobial activity against oral pathogens

In the present investigation, silver nanoparti-cles (AgNPs) and silver nanoparticle-based chitosan nano-composite were synthesized using Cissus arnottiana leaf extract. The biosynthesized nanoparticles and nanocom-posites were characterized using SEM, TEM, and AFM to uncover the morphological characteristics such as size and shape. The SEM image depicts the size of the nanocompo-site to be 30-40 nm and shape as spherical. The TEM results reveal the shape of the nanocomposite to be sphe-rical and size around 10-60 nm. The XRD results show the crystalline nature of the AgNPs-based chitosan nanocom-posite. The SAED analysis pattern seems to be concordant with the XRD results. The AFM image ensured the precise surface morphology of the synthesized silver nanocomposite in the 3-dimensional pattern. The antimicrobial efficacy of the biosynthesized AgNPs, AgNP nanocomposite, and chit-osan nanoparticles was tested against oral pathogens. The results revealed a potential antimicrobial effect, which states that it must be converted into nanomedicine to meet future biomedical needs.
