Green synthesis, characterization, photoluminescence and biological studies of silver nanoparticles from the leaf extract of Muntingia calabura

The current protocol describes the green synthesis of silver nanoparticles, which shown photo-luminescence, antioxidant, anti-inflammatory, antidiabetic and antibacterial effects utilizing leaf extracts of Muntingia calabura. High-throughput methods (UV-Vis, FTIR, XRD, SEM, EDX and PL) were used to characterize the synthesized Mc-AgNP's. The surface plasmon resonance of Mc-AgNP's was detected around 456 nm using UV-Vis spectroscopy. The different functional groups were revealed from the FTIR spectra. The average crystallite size of Mc-AgNP's was found to be 15.52 nm. The morphology of Mc-AgNP's was found as spherical using SEM. Photoluminescence spectrum showed emission around 445 nm with an excitation of 330 nm.(c) 2022 Elsevier Inc. All rights reserved.
