Biological synthesis of nanoparticles has emerged as rapidly developing research area in
nanotechnology across the globe with various biological entities being employed in production
of nanoparticles constantly forming an impute alternative for conventional
methods. Simple prokaryotes to complex eukaryotic organisms including higher plants are
used for the fabrication of nanoparticles. One area of untapped potential is marine
microorganism as nanofactories to fabricate nanoparticles. Marine microorganisms are
known to interact with metal ions as marine ecosystems are constantly exposed to high
metal salt concentration. These microorganisms may reduce the metallic ions rapidly for
the formation of nanoparticles of desired shape and controlled size. The present review
unearths marine microbial flora in synthesis of nanoparticles
