Design Of System In Detecting Aflatoxin Spectrum Based On Induced Fluorescence

The fluorescence spectrum detection technology is widely used in the filed of biochemistry,medicine,industry and chemistry. This is not only because of the high sensitivity of fluorescence analysis but also favorable time scale of fluorescence phenomenon. Fluorescence emittes about 10-8s later than abosorbtion of the light, during this period, many time-different molecure prcesses may occur, and they will influence the spectrum character of fluorescence chemical compound, so we can cerate time resolved fluorescence spectroscopy and phase resolved fluorescence spectroscopy, and these two methods are much helpful to analyze complicated muti-component fluorescence chemical compound and to research many phenomena of biochemistry, the detection of molded grain mass-aflatoxin researched in this paper is based on the advantages of fluorescence detection.Aflatoxin is the metabolite of aspergillus flavus and host aspergillus, of which AFB1 is the strongest chemical carcinogenesis we known and it has the strongest stabilization an toxicity.Aflatoxin exists mainly in chestnut,corn,rice etc, and is the routine detection item in farming industry. The present usual detection methods are enzyme linked immunosorbent assay (ELISA)and Laser induced fluorescence detection(LIF), Though these...
