Ocimum Kilimandscharicum Leaf Extract Engineered Silver Nanoparticles and Its Bioactivity

The present study designed to engineer highly active silver nanoparticle from ELE of Ocimum kilimandscharicum and evaluated its larvicidal potential against Aedes aegypti. The ELE was used for the synthesis of nanoparticle and the synthesized nanoparticle was subjected to instrumental analysis such as UV-Vis spectrum, SEM, EDX and XRD. It was observed from the present study that, the nanoparticles (Ok-AgNps) was spherical, polydispersed, 10 to 50 nm in size, negatively charged and stable in nature. The Ok-AgNps and ELE was studied for its larvicidal efficiency against Ae. aegypti and found promising activity by Ok-AgNps (LC50 value 0.009ppm) than ELE (LC50 value 46.61 ppm). It could be further analyzed for its suitability in mass scale evaluation and toxicity to non-target organisms.
