Amperometric polymer/enzyme composite (PEC) biosensors, incorporating a poly (o-
phenylenediamine) ultra-thin permselective barrier, possess a variety of characteristics that
make them suitable for monitoring brain energy and neurotransmitter dynamics in vivo. This
review highlights PEC sensitivity and selectivity parameters, which allow development of the
basic design in a systematic way in order to improve their performance and to diversify the
analyte range of these novel probes of brain function.
