Green way genesis of silver nanoparticles using multiple fruit peels waste and its antimicrobial, anti-oxidant and anti-tumor cell line studies

. Green synthesis of silver nanoparticles (SNP) opens a new path to kill and prevent
various infectious diseases and also tumor. In this study, we have synthesized silver
nanoparticles using multiple fruit peel waste (pomegranate, orange, banana and apple (POBA)).
The primarily nanoparticles formation has been confirmed by the color change. The
synthesized SNP were analyzed by various physicochemical techniques such as UV- Visible
spectroscopy, x-ray diffraction (XRD), fourier transform infra red (FT-IR) spectroscopy and
transmission electron microscope (TEM). The formation of SNP was confirmed by its
absorbance peak observed at 430 nm in UV-Visible spectrum. Further, the obtained SNP were
identified by XRD and TEM, respectively to know the crystalline nature and size and shape of
the particles. The activities of SNP were checked with human pathogens (Salmonella, E.coli
and Pseudomonas), plant pathogen (Fusarium) and marine pathogen (Aeromonas hydrophila)
and also studied the scavenging effect and anticancer properties against MCF-7 cell lines. This
studies proves that the SNP prepared from fruit waste peel extract approach appears extremely
fast, cost efficient, eco-friendly and alternative for conventional methods of SNP synthesis to
promote the usage of these nanoparticles in medicinal application.
