Biosensors for enantio-sensitive analysis with non-enantiomeric, enant
iomeric and D-and L-enantiomeric enzyme pairs are discussed. These enz
yme pairs can be combined with potentiometric, amperometric, calorimet
ric or optical transducers. Potentiometric biosensors for enantiomeric
analysis are the most advanced, At present, no bio-optodes for enanti
omeric analysis are known.
