[Research on detection of type C2 staphylococcus enterotoxin in food with piezoelectric immunosensors]

Using the biosensor of immobilization of antibody by Piezoectric Immunosensors (PEI) method, the concentration of antigen was determined. When the concentration of antigen was 10 micrograms/L-2 mg/L, the linear response was found. When the sensor was applied to detect type C2 staphylococcus enterotoxin in food, the method was proved with high specificity and selectivity.
