Evaluation of potential antioxidant and effect of biomimetic nanoscale silver particles on opportunistic fungi

Green approach for tailoring quasi spherical Ag nanoparticles (NPs) from leave (L) and rhizome (Rh) of Alpinia Calcarata (AC) was explored due to increasing demand for eco-friendly, efficient, and cost effect antioxidant/antifungal agents. The fabricated Ag particles depicted dose dependence of activities. DPPH radical scavenging rate was about 69.57% and 77.1% at 1.85 × 10^?2 M Ag NPs ACL and Ag NPS ACRh respectively which are attributed to simultaneous activity of surface coverage and small Ag particles. Furthermore, disc-diffusion studies revealed remarkable comparable inhibitory effects of the synthesized Ag NPs ACL and Ag NPS ACRh on all the tested MTCC-4878, MTCC-1811, MTCC-7880 fungi.
