D. indica fruit juice based SNP synthesis has been carried out using previously established method. The SNP were characterized using UV-Vis, furrier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The CSNP were found to be antimicrobial and chemotactic positive. The cytotoxicity against RAW 246.7 (murine macrophage) cell line is found to be moderate at 10% (v/v) of CSNP in culture medium. Moderate toxicity has been observed against Vigna radiata Linn. seed and Oryza sativa (variety Ranjit) seeds. NaBH4 alone and NaBH4 based CSNP is found to be promoting germination of plant seeds.
