Green Synthesis of Silver Nanoparticles from Carrot

The green synthesis method has been widely used for the synthesis of metal NPs due to their environmentally
friendly nature. A bioactive organic natural productsisolated from medicinal plantsexhibit many biological activity viz. antibacterial activity, anti-inflammatory activity, anticancer activity, anti-larvicidal activity etc. The organic natural products-AgNPs nanoconjugates provide an improved biological activity when compared to that of the natural product alone. In the present work,Beta-carotene is isolated from carrot by solvent extraction method. The isolated Beta-carotene is conjugated with the AgNPs by green synthetic method.The Beta-carotene acts as both antioxidant as well as capping agent in the green synthesis of AgNPs.The Beta-carotene-AgNPs nanoconjugates have been characterized by UV-Visible absorption spectral, transmission electron microscopy
(TEM), and X-Ray diffraction (XRD) techniques.The Beta-carotene-AgNPs nanoconjugates can be used for biological applications such as antibacterial activity, anti-inflammatory activity and antioxidant activity.
