Chemical, physical, or biological routes have been beneficial to the synthesis of nanoparticles of varied shapes and sizes. Nevertheless, the synthesis of nanoparticles via the use of plants as precursors is a rapid, environmentally friendly, low-cost option and is safe for the human populace. Synthesis of metal nanoparticles with plant extracts is advantageous owing to their ease of scalability and capability as a capping, bio-reducing mediator, and/ or stabilizer. This study presents a simple and eco-friendly approach for the synthesis of AgNPs, MnNPs, NiNPs, and CuNPs from the leaf extract of Ipomoea involucrata. The synthesized nanoparticles were characterized by UV-UV-visible spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDX), and Fourier Transform Spectroscopy (FTIR). UV-vis spectra of the aqueous medium containing the metal nanoparticles showed a peak at 425 nm for AgNPs, CuNPs at 433 nm, and NiNPs around 416 nm, while MnNPs showed a peak at about 417 nm. The morphology of the metal nanoparticles (IP-MNPs) as documented by the SEM results reveals irregular shapes as peculiar to each nanoparticle. The EDX analysis confirms the presence of each elemental metal in the synthesized nanoparticles. Furthermore, the nanoparticles showed better activities against microbial pathogens than the plant extract; it is therefore suggested that these green-synthesized metal nanoparticles tagged with Ipomoea involucrata can address future health and medical concerns
