Biogenic Synthesis of Sulphur Nanoparticles Using Ocimum Canum Leaves for Antibacterial Application Towards Gram-Positive and Gram-Negative Pathogens

A novel environmentally friendly procedure was used to create sulphur nanoparticles (SNPs) from sodium thiosulphate in the presence of aqueous Ocimum canum leaf extract. SEM, XRD, and FT-IR spectral characterizations were utilized to analyse and validate synthesized SNPs’ successful production. With an average particle size of between 40 and 70 nm, highly crystalline, spherical sulphur nanoparticles were produced. Provisional S. Marcescens and P. aeruginosa (Gram −ve) and B. Subtilis and M. luteus (Gram + ve) were used as human pathogens for the screening of the synthesized sulphur NPs anti-microbial activity, and they were compared to the control antibiotic ciprofloxacin.
