Synthesis, Characterization and Remedial Action of Biogenic Silver Nanoparticles and Chitosan-Silver Nanoparticles against Bacterial Pathogens

Custard apple is a dry land fruit. Its leaves exhibit different pharmacological activities. In the present study, both silver (Ag) nanoparticles and chitosan-coated Ag (Chi-Ag) were fabricated using aqueous leaf extract of custard plant. During preliminary phytochemical analysis, various types phytocompounds found in same Next, physiochemically characterized. FTIR analysis exhibited fingerprint vibrational peaks active bioactive compounds plant extract, nanoparticles, Chi-Ag nanoparticles. UV/Visible spectral revealed highest absorbance peak at 419 nm, indicating presence XRD presented face-centered cubic (FCC) structure prepared nanomaterials. Further, average crystalline size was calculated to be 23 74 respectively. FESEM showed spherical cubical shapes EDS indicated around 3.29 keV, conforming binding energies ions. The biogenic nanomaterial also strong antibacterial activity against all tested bacterial pathogens.
