Abstract

The reaction of naphthoquinone with physiological thiols has been investigated as the basis of a NPT strategy for the measurement of the latter. Screen-printed carbon electrode assemblies provide an inexpensive and inherently disposable platform for the detection methodology. The key analytical parameters underpinning the selective and sensitive (0.4 uM - 1 mM) determination of reduced thiol have been assessed, and the clinical efficacy of the approach has been demonstrated through its application to the analysis of human plasma. The results have been corroborated using standard techniques, and the routes through which the system can be adopted within mainstream biomedical environments are highlighted.
