Nanobiotechnology• Nanotechnology involves the individual manipulation of

single molecules or even atoms. Building components atom-by-atom or molecule-by-molecule in order to create materials with novel or vastly improved properties.

• Nanoparticles are particles of submicron .They are usually spherical, but rods, plates.

Applications of Nanoparticles

• Detection of pathogenic microorganisms and/or specific proteins

• Purification and manipulation of biological components

• Delivery of pharmaceuticals and/or genes• Tumor destruction by chemical or thermal means• Fluorescent labeling and optical coding• Contrast enhancement in magnetic resonance

imaging (MRI)

Applications of Nanoparticles

• Nanoparticles may be used to kill cancer cells by localized heating or local generation of a toxic product

• Nanoparticles may be used to deliver DNA, RNA, or proteins

• Nanocrystals and nanowires may be assembled using unmodified bacteria or sophisticated phage display techniques.

• Detection of viruses by nanowires

Tools of Nanobiotechnology

MICROSCOPY
