Implantable microprobe with arrayed microsensors for combined amperometric monitoring of the neurotransmitters, glutamate and dopamine

► Near-real-time combined sensing of the neurotransmitters, glutamate and dopamine. ► Good selectivity, fast response time, and suitable detection ranges for both analytes. ► No detectable H2O2-mediated crosstalk between Glut and DA microelectrode sites. ► Probe useful for studying the role of Glut and DA in neurological diseases.
