Dry Gongronema latifolium aqueous extract mediated silver nanoparticles by one-step in-situ biosynthesis for antibacterial activities

Abstract In-situ biosynthesis of silver nanoparticles for antibacterial activities doped with aqueous extract of dry Gongronema Latifolium (DGL) is presented in this work. The absorbance was determined using a UV-Visible analysis with a peak of 428 nm. The obtained particles confirmed by the TEM image analysis were spherical in shape with an average particle size between 5 and 20 nm. A single crystalline phase of FCC was confirmed by the powder. The functional groups showed the phytochemical inherent in the sample. The colloidal solution of DGL-AgNPs with MIC of 10 µg/ml showed a noteworthy functional susceptibility against the bacterial strains, particularly, K. pneumonia with susceptibility greater than gentamicin. Based on these observations, the formulated DGL-AgNPs show strong bactericidal against the pathogens with facile, benign, eco-friendly, biocompatibility and innocuous synthesis procedures. This can serve as an efficient bactericidal agent.
