Objective: Biogenesis of multifunctional silver nanoparticles (SNPs) using agro-wastes (paddy straw [PS] and sugarcane bagasse [SB]) was reported in this study that could be deployed for biomedical and environmental applications.

Methods: The SNPs were synthesized using agro-waste extracts and the synthesized SNPs were characterized by ultraviolet (UV)–visible spectrophotometry, scanning electron microscopy, Fourier-transform infrared (FTIR) spectroscopy, and energy dispersion spectral (EDS) analysis and evaluated for their multifunctional applications.

Results: UV–visible absorption scan of SNP revealed a broad peak at 420 nm indicative of the surface plasmon resonance using 10 mM silver nitrate with the reaction time of 24 h for PS SNP and 10 min for SB SNP. The synthesized SNPs were of size ranges from 50 to 70 nm. The SNPs were investigated to evaluate the antimicrobial activity against pathogens, efficacy in sewage water treatment and in biofilm inhibition.

Conclusion: This study has demonstrated the eco-friendly synthesis of SNPs using the agro-wastes. The synthesized NPs displayed remarkable antimicrobial activity, biofilm inhibition, and in sewage water treatment. These activities have shown that these NPs can find useful biomedical and environmental applications.
