In this study, a method for the detection of C-reactive protein (CRP) using laser is proposed. Lasers are devices that produce intense beams of light which are monochromatic, coherent, and highly collimated. The wavelength (color) of laser light is extremely pure (monochromatic) when compared to other sources of light. C-reactive protein (CRP) is an annular (ring shaped), pentameric protein found in blood plasma, it measures general levels of inflammation in our body. It was so named because it was first identified as a substance in the serum of patients with acute inflammation. High levels of CRP are caused by infections and many long-term diseases. Burns, trauma, certain cancers are the main causes of elevated c reactive protein. It aims to characterize and optimize the process for significantly increasing the quantum yield of CdSe quantum dots suspended by coating them with a ZnS. To accurately test the effects of a ZnS coating on CdSe quantum dots, a process flow had to be developed to synthesize, coat, and characterize the quantum dots. After synthesizing the CdSe quantum dots, they were characterized, then coated with ZnS, and characterized again. Following this procedure, we can direct compare between coated and uncoated quantum dots to be made, thus characterizing the effects of the ZnS coating process.
