GOLD NANO PARTICLES - Essay Example variations that are used in comprehension of plasomons which depends on the wavelength, otherwise known as conduction-band electrons during oscillation. This phenomenon translates into absorption and scattering ability of light, which is an important feature to biological applications like sensing and imaging. The ability of bio molecules to interact both inside and at the surface of a cell can result into varied interactions according to the size of nanoparticle. Currently, for medical sector purposes, it is possible to modify and fabricate nanoparticles and AUNPS is best for clarifying the distinct properties of the â€Å"red surface Plasmon resonances band at 520† with catalytic activity which is high and easily fabricated with the use of thiol interconnected to SS-DNA which enables them to be components that are stable for bio-sensing purposes. When nanoparticles and biological elements of lipids, proteins and nucleic acids are combined, they can reveal specific functions in bioprobes and biosensors. It is therefore, important to note that, nanoscale particles possess clear and exceptional potential of detecting and accurately diagnosing cancer (Chan 2007). To increase the level of sensitivity like in surface enhanced Rayleigh scattering, surface enhanced fluorescence, and surface enhanced Raman scattering, the use of surface Plasmon have been significant. Though, SERS is an attractive and has very unique technique that can be vital in measuring rotational, vibration and molecules of low transition frequency based on Raman scattering (Chan
