In this study, strontium oxide nanoparticles (SrO NPs) were successfully synthesized using Solanum nigrum leaf extract. The extract acted as a stabilizing agent during the synthesis process. Characterization techniques such as FTIR spectroscopy confirmed the existence of functional groups of the nanoparticles. Photon Correlation Spectroscopy analysis revealed an average particle size of 94.8 nm with a polydisperse distribution. SEM images showed the morphology of the nanoparticles, ranging from individual particles to agglomerates. XRD analysis indicated a cubic crystal structure for the SrO NPs. Importantly, the synthesized SrO NPs exhibited significant antibacterial activity against Mycobacterium TB, Candida albicans, and E. coli, highlighting their potential as antimicrobial agents. This eco-friendly approach utilizing Solanum nigrum extract opens up possibilities for the green synthesis of SrO NPs with promising biomedical applications.
