Najafpour Faculty of Chemical Engineering Noshirvani Institute of Technology Mazandaran University Babol Iran Accepted 14 July 2006 Bovine serum albumin BSA was used for generation of nanoparticles in a drug delivery system.

Biological systems are the masters of ambient condition chemistry and are able to synthesize nanoparticles by utilizing metal salts. In the perspective of the current initiative to develop green. Nanoparticles synthesis by fungi.

Biological production of nanoparticles by fungi is determined nowadays because of their reception towards toxicity higher bioaccumulation comparatively economic effortless synthesis method and simple downstream processing and biomass handling. Extracellular biosynthesis of nanoparticles by Aspergillus niger Fusarium solani and Aspergillus oryzae are produce in Nanoshel. The biological process with the ability to study the shape of particles produced would therefore be a limelight of modern nanotechnology.

The bacterial strain Escherichia coli used for the biosynthesis of silver nanoparticles were investigated. These silver nanoparticles were characterized by means of UVvis spectroscopy particle size analyzer. The production of nanoparticles with specific properties is an important branch of nanotechnology.

Nanoparticles can be linked to biological molecules that can act as address tags directing them to specific sites within the body specific organelles within the cell or causing them to follow specifically the movement of individual protein or RNA molecules in living cells. Synthesis Fungus Fusarium oxysporum. It has been found that initially Au is reduced followed by Ag leading to nanoparticles of Au-Ag alloy.

Depending on the biomass of fungus used one can change the composition of the alloy nanoparticle formed from pure Au to pure Ag with increase in the biomass concentration Process involved in nanoparticle synthesis by fungi Screening of fungi F. Oxysporum and Verticilium sp. Culturing and Biomass harvesting Biomass.

The biological production of highly stable and well-characterized nanoparticles can be obtained by optimizing vital aspects such as types of organisms cell growth and enzyme activity optical growth and reaction conditions and suitable biocatalyst. An alternative way of synthesising metallic nanoparticles is by using living organisms such as bacteria fungi and plants. This green method of biological nanoparticle production is a promising approach that allows synthesis in aqueous conditions with low energy requirements and low-costs.

An alternative way of synthesising metallic nanoparticles is by using living organisms such as bacteria fungi and plants. This green method of biological nanoparticle production is a promising. Green synthesis of nanoparticles using plants has become a promising substitute for the conventional chemical synthesis methods.

In the present study our aim was to synthesize chromium oxide nanoparticles Cr 2 O 3 NPs through a facile low-cost eco-friendly route using leaf extract of Rhamnus virgata RV. Biological synthesis of nanoparticles germinated from the experiments on biosorption of metals with Gram negative and Gram positive bacteria. The synthesized molecules were not identified as nanoparticles but as aggregates Mullen et al 1989.

Fundamental Concept of Nanobiotechnology Nanotechnology is the engineering of. An array of physical chemical and biological methods have been used to synthesize nanomaterials. In order to synthesize noble metal nanoparticles of particular shape and size specific methodologies have been formulated.

Although ultraviolet irradiation aerosol technologies lithography laser ablation ultrasonic fields and photochemical reduction techniques have been used successfully. Due to the photoelectric semi-conducting and X-ray-sensing properties selenium is an element of great economic potential. Since nanomaterials display special properties compared to bulk particles the production of selenium nanostructures wires rods or spherical particles has attracted much attention.

In this study alternative approaches to classical synthesis were investigated producing selenium. DIFFERENT BIOLOGICAL METHODS FOR NANOPARTICLE SYNTHESIS 10. Synthesis of Nanoparticles from Bacteria Bacteria have been most extensively researched for synthesis of nanoparticles because of their fast growth and relative ease of genetic manipulation.

METHODS OF SYNTHESIS Intracellular. Inside the cell in cytoplasm or cytosol. Biological hydrogen H2 production enhancement through the use of nanoparticles NPs supplement in the media is being recognized as a promising approach.

The NPs including those of metal and metal oxides have shown a significant improvement in the BHP. A number of organisms as pure or mixed cultures can produce H2 in presence of NPs from pure sugars and biowaste as a feed. However their H2 production.
