Stochastic Sensors Based on Diamond Paste for Screening of Biological Fluids for Neurotransmitters

Diamond paste proved to be one of the best matrices for the design of stochastic sensors. Therefore, different porhyrins were immobilized in diamond paste.

The “signatures” of neurotransmitters were determined. The “signatures” were used to identify these analytes on the diagrams obtained when whole blood was screened. Quantitative analysis was also performed using these microsensors. The results obtained using the proposed microsensors were correlating very well with those obtained using the standard methods used in clinical analysis.
