摘要：

Different signal generation techniques were investigated for the development of a biosensor for Listeria monocytogenes. Conventional amperometry at an antibody-containing polypyrrole film electrode was found to be unsuccessful in detecting levels below 10(6) cells ml(-1). More successful was the coupling of a covalently modified film with the use of electron mediators in a single device. This sensor was capable of reproducibly detecting Listeria at levels of 10(5) cells ml(-1) in 30 min. (C) 2002 Elsevier Science B.V All rights reserved.
