7 Microorganism isolated from array of habitats have expressed immense potential in production of nanoparticles one such habitat is marine. Marine microorganisms are known to thrive in unique niches such as tolerate high salt concentration, extreme atmospheric pressure etc. These microbes

are known to have been explored with interest as source of novel bioactive factories synthesizing various functional metabolites displaying unique properties. However, these marine microbes are not sufficiently explored with regards to synthesis of nanoparticles few reports cited expressed the burgeoning interest among the researchers learn more in exploiting the mechanisms of marine microbes for nanoparticle synthesis. As marine resource is one of the richest sources in the nature, marine microorganisms employed in production of nanoparticles are in infancy stage. Therefore, a possibility of exploring marine microbes as nanofactories forms a rational and reliable route in production of nanoparticles compared to the most popular conventional methods

which are bound with limitations such as expensive, use of toxic elements selleck compound in production protocols resulting limited applications in pharmaceutical and health sector. The present review envisions the role of marine microbes as emerging resource in synthesis of nanoparticles. The study also display so far reported marine microbial diversity in synthesis of nanoparticles, further research in this area will be promising enough to engulf the limitation of conventional methods forming a new avenue for rapid synthesis of nanoparticles with technical dimension. Nanoparticles are particles with at least one dimension at nanoscale. Nanoparticles exist widely in the natural world as product ADP ribosylation factor of natural phenomena such as photochemical

volcanic activity, ocean spray, forest-fire smoke, clouds and clay combustion and food cooking, and more recently from vehicle exhausts.3 Owing to their unique properties nanoparticles are known to have wide range of applications the potential of nanoparticles is infinite with novel new applications constantly being explored.4 Nanoparticles are synthesis by array of conventional methods which are divided into top down and bottom up processes (Fig. 1). In top down process the synthesis of nanoparticles from the bulk material is carried out by various lithographic techniques. In bottom up process is based on miniaturization at molecular level forming the nuclei and their growth into nanoparticles. These conventional methods are very popular and widely employed in synthesis of nanoparticles but are bounded with their own limitations such as expensive, use of high energy and use of hazardous toxic chemicals. Hence there is a burgeoning interest in eco-friendly process of nanoparticles production with precise control of size and desired shape.
