- Abstract
Biologically synthesized metal-oxide nanoparticles (NPs) are in focus for their multifarious applications. In the current study, the green synthesis of copper oxide NPs (CuO NPs) is achieved using the fresh biomass of Cylindrospermum stagnale after its molecular characterization. Physical characterization of CuO NPs by several analytical techniques including UV–Vis analysis, FT-IR spectroscopy, SEM and TEM microscopy revealed spherical shaped crystalline CuO-NPs capped by functional groups of cyanobacterium biomolecules with slight aggregation. CuO NPs were found significantly antimicrobial against pathogens with MICs of 1.5, 2.4, 1.7, 2.5, and 0.6 mM against Candida albicans, Klebsiella pneumoniae, Enterobacter cloacae, Pseudomonas aeruginosa, Escherichia coli, respectively. Moreover, cyanobacterium-capped CuO NPs were cytotoxic against HepG2 cell line and effective against larvae of Aedes ageypti, Anopheles subpictus Grassi and Culex quinquefasciatus. The synthesized CuO NPs were effective due to their high surface area and fairly small size 12.21 nm. Due to adequate biological activities of cyanobacterium CuO NPs even at lower concentrations, we prospect these NPs for clinical applications.
