Environmentally Friendly Process

The development of an environmentally friendly process for the synthesis of metal nanoparticles is an important step in the field of nanotechnology. One way to achieve this goal is to use biological systems. In this study, silver nanoparticles were obtained using extracellular enzymes of organisms of the Saccharomyces boulardi strain. The effect of the pH of the medium on the synthesis of nanoparticles was studied. The antimicrobial activity of the obtained nanoparticles was investigated.

Synthesis Of Nanoparticles

Though there are a numerous methods for chemical synthesis, biogenic synthesis of nanoparticles offers an attractive alternative to chemical synthesis methods. Therefore scientists are continuously engaged in searching hazard free, environment friendly methods of synthesis of nanoparticles with tailor-made structural properties using benign starting materials. Recently several groups have achieved success in the synthesis of Ag, Au, Pd nanoparticles with specific shape and size using extracts obtained from micro-organisms as well as various plant extracts. It will be a highly interesting problem to modify the procedure to develop green-chemical means of synthesizing “tailor-made” monodisperse nanoparticles of single polygonal particle morphology, exclusively. The main objective of this brief article is to give an idea about the most reliable, cost-effective and environment friendly synthetic protocols for metal nanoparticles of different size, shape, composition, and with a high degree of monodispersity.

Green Technique

: Metal nanoparticles are nanosized entities with dimensions of 1-100 nm that are increasingly in demand due to applications in diverse fields like electronics, sensing, environmental remediation, oil recovery and drug delivery. Metal nanoparticles possess large surface energy and properties different from bulk materials due to their small size, large surface area with free dangling bonds and higher reactivity. High cost and pernicious effects associated with the chemical and physical methods of nanoparticle synthesis are gradually paving the way for biological methods due to their eco-friendly nature. Considering the vast potentiality of microbes and plants as sources, biological synthesis can serve as a green technique for the synthesis of nanoparticles as an alternative to conventional methods. A number of reviews are available on green synthesis of nanoparticles but few have focused on covering the entire biological agents in this process. Therefore present paper describes the use of various living organisms like bacteria, fungi, algae, bryophytes and tracheophytes in the biological synthesis of metal nanoparticles, the mechanisms involved and the advantages associated therein.
