Microwave-assisted CdS nanoparticles were prepared using plant extract (Andrographis paniculata) and studied by using structural, morphological, optical, and antibacterial analysis. The results revealed a hexagonal structure of CdS nanoparticles with an average crystallite size of 19 nm. The FTIR peak at 601 cm-1 confirmed the vibration stretching of Cd-S bonds. SEM and TEM images demonstrated rod-like morphology of the nanoparticles. The optical bandgap of the prepared CdS nanoparticles was found to be equal to 2.51 eV. The photodegradation activity of the prepared nanoparticles for Rose Bengal dye was evaluated under sunlight irradiation. The degradation of the dye was equal to 99 % after 120 min. The antibacterial activity of CdS nanoparticles investigated against human pathogens indicated higher antimicrobial activity against gram-positive (S. aureus) as opposed to gram-negative (E.coli, E. typhi and P. aeruginosa) bacterial strains.
