Development of a piezoelectric immunosensor for the detection of enterobacteria.
A piezoelectric crystal immunosensor has been developed for the detection of enterobacteria in drinking water using antibodies against the enterobacterial common antigen. Applying an anti-enterobacterial antibody layer via protein A immobilization onto a 10-MHz crystal, a response is observed for 10(6) to 10(9) cells ml-1 of Escherichia coli K12, and for various other antigens of the Enterobacteriaceae family.
