Study on Fluorescent Detection Glucose Molecule Marked with ZnSe Nano Crystalline in Microchannels

Shell-core structure of ZnSe nano crystalline cluster is used for marking glucose molecules in this paper. Fluorescent detection is successfully realized in microchannels. Mercaptoacetic acid is used for packing ZnSe nano crystalline cluster, which is dissolved in the water. Carboxyl of mercaptoacetic is used for connecting glucose molecule, and mixture solution of glucose molecule marked with ZnSe nano crystalline cluster is inleted by capillary force in muti-microchannels with diameter of 30 microns. Exciting light with the wavelength range from 265nm to 420nm is used for stimulating glucose molecules marked with ZnSe nano crystalline cluster in multimicrochannels, and fluorescent detection is carried out for glucose molecules. It is concluded that shell-core structure of ZnSe nano crystalline cluster is feasible for marking glucose molecules. The new method will lead to new application in many fields such as biologic analysis, biosensor, biologic detection and spaceflight, and so on.
