synthesized gold nanoparticles was centrifused at high speed. The pellet and supernatant liquid were separated. The pellet was again dispersed in milli-Q water. The synthesis of gum tragacanth gold nanoparticles was optimised temperature and reaction time. The effects of concentration of gum tragacanth (0.1 to 1%) and concentration of HAuCl4 (0.1 to 1 mM) on the synthesis of gold nanoparticle were studied. The synthesized AuNPs were stored in amber color vials at 4oC. The nanoparticle formulation showed

Introduction: Over the past three decades we have witnessed a tremendous amount of activity in the area of biosensors. Biosensors are small devices employing biochemical molecular recognition properties as the basis for a selective analysis. The major processes involved in any biosensor system are analyte recognition‚ signal transduction‚ and readout. Due to their specificity‚ speed‚ portability‚ and low cost‚ biosensors offer exciting opportunities for numerous decentralized clinical applications

citrate would change the colour of a gold solution. Meaning the hypothesis was: if more sodium citrate is added the nano particle size will increase and the colour of the gold solution will move towards the red end of the spectrum. Theory Nanoparticles are different colours because of the way the electron waves at the edge of the matter interact with the light spectrum. A change in particle size will change the colour of the matter; another factor which affects the colour is the shape the particles

There are a number of diseases and medical problems which can be treated by taking different routes. It has become possible to treat certain conditions by delivering drugs or nutrients to the body with the help of liposomes. Liposomes are artificially engineered vesicles within a lipid bilayer. (Lee‚ 2006) There are various methods by which liposomes can deliver the needed substances. One of these ways is to create a PH gradient between the solution and the liposome. As the pH neutralizes the drug
