Microwave assisted biosynthesis of silver nanoparticles using banana leaves extract: Phytochemical, spectral characterization, and anticancer activity studies

Microwave assisted biosynthesis of nanoparticles has been a cost effective, environmentally benign, and alternative to the chemical method. In this context, we report ecofriendly and robust nanoparticles synthesized using the biowaste (Banana leaves) extract material through a microwave method. The newly synthesized Banana Leaves extract Silver Nanoparticles (BLAgNPs) is confirmed by using the UVVisible, FTIR spectroscopy and Scanning Electron Microscopy (SEM) techniques. UVVis spectrum shows the widening of the band around 476 nm, which confirms the polydispersed nature of BLAgNPs. FTIR spectroscopy explores that, hydroxyl and carbonyl groups in the Banana Leaves extract play vital role in the reduction of silver ions and also attach with AgNPs. The phytochemical studies reveal that, the polyphenols and alkaloids present in the BL extract act as reducing and stabilizing agent, which is responsible for the reduction of Ag+ (silver ions) to Ag (BLAgNPs) and stabilization of BLAgNPs. This clearly confirms the formation of silver nanoparticles (AgNPs). SEM results revealed that, bead shape of BLAgNPs with particle size of 80 to 100 nm. In conclusion, BLAgNPs exhibits promising anticancer activity against lung cancer and breast cancer cell line by endorsing inhibition of cell migration and proliferation on low concentration.
