How Protein Labeling Applying

Abstract

In recent years, biosensing has played an irreplaceable position in scientific fields as well as our daily lives. A biosensor is an instrument that is sensitive to biological substances and converts its concentration into electrical signals for detection. It is an analysis tool or system composed of immobilized biologically sensitive materials as identification elements, appropriate physical and chemical transducers and signal amplification devices, and it has the functions of both a receiver and a converter. Pregnancy test sticks, blood glucose testing, etc. in life are all potential biosensors. The main point of this paper is to introduce several main techniques of biosensing for better understanding, like ELISA, fusion proteins, fluorescent probe and others. In the future, the bright future for them is also worth looking forward to if more researches and experiments can be processed in this area, for example, in the detection and treatment of cancer, medical technology can be further improved.
