Palm-size wireless piezoelectric immune-biosensing system for rapid E. coli O157:H7 detection
Summary
A palm-sized, wireless immunosensor for E. coli O157:H7: a gold QCM carrying protein A-anchored antibodies, a PDMS microfluidic channel and a flexible loop antenna, with results sent by Bluetooth to a smartphone app. The frequency shift grows with bacterial concentration, immuno-nanobeads amplify the signal, and the system reached about 10² CFU/mL in field samples with little cross-reaction to other bacteria.
