N2 - Today, cadmium sulfide nanoparticles are extensively used in various fields, including medical sciences, engineering, drug delivery, photovoltaic cells, bio-imaging techniques, molecular pathology, and bio-sensing. This study uses a green, eco-friendly approach to explore biosynthesized CdS NPs characterization and their antibacterial activity. A uniform color change from light yellow to greenish yellow indicated the formation of cadmium sulfide nanoparticles, further confirmed by a blue shift at 450 nm in optical absorption spectra. The XRD (X-ray diffraction) analysis confirmed the crystallinity of elements present in nanoparticles, while the coating of Coronopus didymus phytochemicals around the nanoparticle surface was confirmed by Fourier transform infrared (FT-IR) analysis. Next, SEM analysis was performed to investigate the morphology and size of the CdS nanoparticles. The antibacterial activity of the synthesized CdS nanoparticles was evaluated against gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae) and gram-positive bacteria (Staphylococcus aureus); their result shows the highest zone of inhibition at a medium concentration of 40 mg/ml in Klebsiella pneumoniae (27.5±0.70), Escherichia coli (21.5±0.70), and Staphylococcus aureus (12.15±0.25). Our approach presents a successful, green, and cost-efficient method for synthesizing CdS nanoparticles and exploring their antibacterial activity.
