Green synthesis of silver nanoparticles using polar seaweed Fucus gardeneri and its catalytic efficacy in the reduction of nitrophenol
Biofabrication of metal nanoparticles via seaweeds is quite interesting as it make use of phytochemicals in the aqueous seaweed extract as sole bioreductant and stabilizing agent. Herein, we report for the first time, the utilization of a Polar seaweed Fucus gardeneri for the biosynthesis of well st...

Biofabrication of metal nanoparticles via seaweeds is quite interesting as it make use of phytochemicals in the aqueous seaweed extract as sole bioreductant and stabilizing agent.

As no harmful chemicals employed in the synthetic procedure, it is absolutely a green chemistry procedure.
