Alpinia nigra fruits mediated synthesis of silver nanoparticles and their antimicrobial and photocatalytic activities.

In the present systematic study, silver nanoparticles have been synthesized using the fruits of Alpinia nigra. Apart from the presence of saponins, glycosides, alkaloids, steroids, the extract of A. nigra fruits are rich in polyphenols.

Biogenic synthesis of gold nanoparticles and their application in photocatalytic degradation of toxic dyes.

Plants and their extracts play an important role in the green synthesis of nanoparticles mainly because of their environmental benignity. Based on plant extracts number of metal nanoparticles have been synthesized. In our study, we report a green technique for the synthesis of gold nanoparticles using the aqueous extracts of Alpinia nigra leaves and their photocatalytic activities.
