Thin Film Microsensor for Electrical and Optical Blood Diagnostics

Abstract:

Article Preview

Thin film microsensor (TFμS) consisted of interdigitated arrays of electrodes (IDAE) for electrical and optical monitoring of the aggregation phase of erythrocyte sedimentation has been developed. Planar TFμS is based on IDAE, Pt or transparent conductive ZnO:Al thin films sputtered on ceramic or glass substrates. It allows single or simultaneous measurements of electrical impedance (10÷100 kHz) and optical absorbance/transmittance (320÷800 nm) of small blood drop applied on TFμS. Time monitoring of these parameters (in the first 300 sec) can distinguish between healthy and cancer state of blood and could serve as screening method for early diagnoses or for the simple long-term diagnostics after surgical operation.
