ELECTROCHEMICAL BIOSENSOR AND A METHOD OF SENSING ALBUMIN AND ITS COMPLEXES

摘要

An electrochemically active device for collecting and retaining a biological sample with a bioanalyte the device provided with at least a two electrode member and an albumin binding and an electrochemically active receptor in chemical contact with the two electrode members and the biological sample. The present invention also provides a point of care biosensor with the device of the present invention and a method for measuring a bioanalyte in a biological sample. The device point of care biosensor and the method of the present invention facilitate accurate measurements concentrations of urine albumin human serum albumin (HSA) glycated albumin (GA) and methemalbumin (MHA) by determining redox current values in reduced volumes of biological samples.
