Green Synthesis and Characterization of Biologically Active Silver Nanoparticles Using Perilla frutescens Leaf Extract

Silver nanoparticles (AgNPs) were synthesized using an aqueous Perilla leaf extract and evaluated for anticancer activity. These green -synthesized AgNPs were characterized using UV–Visible absorption spectroscopy, XRD, TEM, and SAED. The synthesized AgNPs were spherical and hexagonal in shape, and the average size of the NPs was ~23 nm. SRB assay investigated the anticancer activity of the AgNPs against human cervical cancer (HeLa) cells. The fluorescence and confocal microscopy studies were confirmed the DNA damage and apoptosis following nanoparticle treatment. Furthermore, the intracellular ROS was also increased after treatment. Taking all these data together, it is suggested that AgNPs may be a potential agent for the inhibition of cervical tumor cells.
