Abstract :
Electrical determination of E.coli O157:H7 was investigated by antibody-modified individual SnO2 nanowire (TONW) coupled with microfluidic chip. The static responses to E.coli and S.typhimurium on new device were studied. The responses to E.coli on the device that contained an unmodified or a modified TONW under continuous injection were also compared. Finally, an alternative mechanism to explain the observed behavior was proposed
