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 photoluminescence, antioxidant, anti-inflammatory, antidiabetic and antibacterial effects utilizing leaf extracts of Muntingia calabura. High-throughput methods (UVeVis, 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 UVeVis 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.
