Biosynthesis and characterization of copper oxide nanoparticles from indigenous fungi and its effect of photothermolysis on human lung carcinoma

In this report, copper oxide nanoparticles (TA-CuO NPs) were synthesized using cell-free extract of Trichoderma asperellum and assessed their photothermal induced anticancerous activity. The fungal mediated TA-CuO NPs was confirmed by the surface plasmon resonance at 285–295 nm. The amide (CO) and aromatic (CC) groups in secondary metabolites of the extract was found to be an encapsulating or reducing agents for TA-CuO NPs, as indicated by IR spectra. Crystalline nature by cubic face-centered structure of the TA-CuO NPs was confirmed by XRD and their size ranges from 10 to 190 nm and an average of 110 nm by particle size analyzer (PSA). The Ultra HRSEM study revealed spherical shaped TA-CuO NPs. The FETEM results were also in strong agreement with PSA and UHR SEM. The survey-scan s...
