Download file to see previous pages 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 “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 ...Download file to see next pagesRead More

Nano-Thermal Analysis
since during the manufacturing of the drug various factors such as change in temperature and moisture can alter its toxicity, actions, kinetics and dynamics as well.(Giron,2002).To understand the solid state properties and the key to efficient characterization of the compound is to formulate a strategic technique and elaborate analytical programs that enables us to understand the chemical, structural, energetic and physical states of the compound.(Lee,2003) Fundamental properties that need to be analyzed in a solid dosage form Test Method/ function Characterization Fundamental properties 1) UV spectroscopy Simple assay 2) Solubility Phase solubility/ purity 3) Melting point DSC-polymorphism

THE ROLE OF CONTROLLED DRUG RELEASE IN CANCER THERAPEUTICS
The disease is also known as malignant neoplasm since the cells grow continuously without control forming malignant tumours (Wolinsky, Colson and Grinstaff 2012, p.444). Cancer cell fail to follow the normal cell cycle, whereby after sometime the cell needs to die, a process called apoptosis (Blanco Hsiao, Mann, Landry, Meric-Bernstam and Ferrari 2011, p.342).

Nano- and Micro-Technology
It is essentially the engineering of functional systems at the molecular scale. It involves, penetrating down the nano-scale level i.e. one billionth of a meter or 1/100,000 the width of a human hair. The concept picked up when Richard Feynman in one of his talks way back in 1959 mentioned the progress made by science in the field of miniaturisation, he asked, "Why cannot we write the entire 24 volumes of the Encyclopaedia Britannica on the head of a pin" subsequently he went on to profess that it is just a matter of time, before we could actually see it happen.
