A laser-based approach for detecting C-reactive protein (CRP) is proposed in this study. Laser beams are devices that generate powerful monochromatic, coherent, and heavily collimated beams of light. When in comparison to other light references, the range of frequencies (colour) of photons from a laser is exceptionally solid (monotonous). C-reactive protein or CRP is a pentameric, protein with an annular shape present in plasma from the bloodstream that monitors overall levels of inflammation in the body. It got its name since it was initially discovered in the serum of patients suffering from acute inflammation. Infections and numerous long-term disorders create high levels of CRP. Burns, trauma, certain cancers are the main causes of elevated c reactive protein. Its goal is to characterise and optimise the technique of coating CdSe quantum dots suspended in ZnS to considerably increase their quantum yield. To effectively study the effects of a ZnS covering on the quantum dots, a current process for synthesising, covering, and evaluating CdSe quantum dots had to be developed.
