Facile fabrication of CuO nanoparticles via microwave-assisted method: photocatalytic, antimicrobial and anticancer enhancing performance

Abstract

In this current research, biogenic Copper oxide (CuO) nanoparticles were successfully produced by the green method, i.e. microwave-assisted process using Andrographis paniculata as a source. Microwave-assisted biogenic CuO nanoparticles were investigated with various instrumental techniques. The micrographs of the FESEM and TEM showed that the size of particles is around 30 nm. In addition, the photocatalytic performance of CuO nanoparticles was conducted against the methylene blue (MB) dye in the presence of natural sunlight irradiation. Further, antimicrobial activities of the biogenic CuO nanoparticles were tested against foodborne pathogens. The CuO nanoparticles showed anti-cancer (A549: IC50:14.76 µg/mL) activity and they are biocompatible in nature. In addition, biogenic CuO nanoparticles can be applicable to toxic pollutant treatment and pharma drug applications.
