An insect-based bioFET as a bioelectronic nose

摘要

By coupling the insect antenna of a potato beetle to the gate of a filed-effect transistor,a biosensor sensitive to Z-3-hexen-1-ol has bene realized.This Isolated-antenna BioFET allows the rapid and quantitative determinatoion fo the characteristic green-leaf odour doswn to the ppb range.Due to its miniaturizable set-up,such a biosensor offers the possibility of field measurements,e.g.the investigation of plant damages in glass-houses.
