A NOVEL PROCESS TO PREPARE SILVER NANO-PARTICLES FROM OCIMUM SANCTUM (THULASI) AND PIPER BETLE

摘要

ABSTRACT The invention relates to a novel process to prepare Silver nano particles from Ocimum sanctum (Thulasi) and Piper betle (betelleaf). The Silver nano particles (AgNPs) are nano particles of silver between 1 nm to 100nm in size. They are known to have excellent antimicrobial properties thus used as disinfectants. AgNPs are synthesized by different methods viz., physical, chemical and biological. The biological or green synthesis of AgNPs is most preferred method than the chemical and physical methods as they are eco friendly, economic and easy for large scale synthesis. The present invention discloses the antibacterial activity of AgNPs prepared by the aqueous extracts of Ocimum sanctum (Thulasi) and Piper betle (betel leaf) against E. faecalis.
