Antimicrobial activities of biosynthesized nanosilver using Musa paradisiaca and Citrus sinensis peel extracts against major human and plant pathogens.

ABSTRACT: This study was aimed to evaluate the antimicrobial activities of silver nanoparticles (AgNPs) biosynthesized from aqueous extracts of banana (Musa paradisiaca L.) and sweet orange (Citrus sinensis L.) peels. The AgNPs were successfully biosynthesized using specific amounts of powdered banana and orange peel extracts along with AgNO₃ as a precursor. A noticeable color change in the AgNP solutions, shifting from yellow to dark brown after 24 h, served as an initial indicator of AgNP formation. UV-Vis spectrophotometer and powder XRD absorption spectra for both banana peel-AgNPs (BPAgNPs) and orange peel-AgNPs (OPAgNPs) exhibited distinct peaks confirming the presence of AgNPs. Furthermore, FTIR spectra indicated the presence of phenolic compounds that contribute to AgNP synthesis.
