✦ Synopsis

A biosensor strategy for rapid amperometric detection of organisms was investigated in which a redox mediator was entrapped within liposomes. The selective release of mediator by haemolytic bacteria, followed by signal generation, confers differentiation between haemolytic and non-haemolytic species. The potential of this approach is illustrated by results for various strains of Listeria monocytogenes, Listeria welshimeri and Escherichia coli.
