Nanoparticles are small molecules with size ranging between 1-100nm. Basis of their classification is their properties shapes and size. These find usage in wide range of industries from agricultural, biomedical, environmental and food. There are numerous ways of producing these nanoparticles using chemicals and biological means. Use of various micro-organisms (biological process) is highly effective in producing high quality, toxin free and cost effective nanoparticles. In this context, present article concerns with association of bacteria with nanoparticles. Here “Green Synthesis” of nanoparticles through the use of different bacteria is discussed. Contrasting nanoparticles such as cadmium, silver, copper, zinc, gold, platinum, magnetic, tellurium etc. can be synthesized through various bacterial species like Bacillus cereus, Pseudomonas antarctica, Shewanella algae, Deinococcus radiodurans, Xanthomonas oryzae, Alcaligenes faecalis, Neurospora crassa, Rhodopseudomonas capsulata, Arthrobacter kerguelensis etc.

Nanoparticles and bacteria are used in association for different applications an over view of which is presented in the articles. Also, the association among the two for the drug delivery to the target site has been looked upon.

Nanoparticles are of size 1-100nm and can be made from carbon, metal oxides or other organic matter [1]. All the nanoparticles have ability to show distinguished biological, physical and chemical properties at Nano-scale. Nanoparticles exhibit properties like increased reactivity and stability in a chemical processes, enhanced mechanical strength etc. [2]. These have gathered much attention because of different and interesting properties, applications and advantages over their bulk counterparts. Nanoparticles are of different shape and sizes like zero dimensional e.g. nanodots, one dimensional e.g. graphene, two dimensional e.g. carbon nanotubes, three dimensional e.g. gold nanoparticles. They can be hollow core, cylindrical, spherical, conical, tubular, spiral, flat or even irregular in shape [3]. They also differ in structure which can range from amorphous to crystalline with one or more crystals [4,5]. Nanoparticles have biomedical applications and thus eco-friendly and nontoxic methods should be used for their synthesis. The preferable way to synthesize nanoparticles is by using micro-organisms, which is the most superior method as well as cost effective [6]. Use of micro-organisms is energy efficient and environmental friendly way to produce nanoparticles which can be used to perform functions like drug carrier for target delivery, gene therapy, DNA analysis, biosensor, MRI [7].

Thus it can be said that different micro-organisms play a vast role in production of industrially important nanoparticles. Taking this into consideration, the present article includes an overview of nanoparticles, used of various micro-organisms (especially bacteria) in production of different kind of nano particles and their applications.
