A novel approach towards green synthesis of silver nanoparticles from Bignonia Venusta (L.) for their biocompatibility studies. (Funded work)
In recent years, the green synthesis of nanoparticles using various plant extracts has attracted great attention as these methods are simple, inexpensive and, eco-friendly. In the present investigation an attempt has been made for green synthesis of silver nanoparticles using plant extracts of lessThan i greaterThan Bignonia venusta lessThan /i greaterThan (L.) lessThan i greaterThan . lessThan /i greaterThan In this study, it was observed that the plant extracts lead to the formation of crystalline silver nanoparticles. lessThan i greaterThan Bignonia venusta lessThan /i greaterThan (L.) is known as a rich source of flavonoids, steroids, tannins and other phenolic compounds. The AgNPs prepared by green synthesis methods were monitored by measurements of FT-IR. Further morphology and size were determined by SEM and TEM. The size of AgNPs varied between 50 nm and 100 nm. XRD was done to study diffraction which denotes crystal structure of AgNPS. The AgNPs were tested for antimicrobial, antioxidants activity. Maximum antimicrobial activity was observed against lessThan i greaterThan Streptomyces grisveus lessThan /i greaterThan at 40 µg/ml (20 mm) while in fungus no activity was observed.
