Diagnostic Ex-Vivo Assay of glucose Using Diabetic-Control Circuits

Abstract

For ex-vivo diabetic control, the voltammetric diagnosis of glucose (GU) was conducted with a modified carbon nanotube paste electrode, using handheld analytical circuits. The optimum analytical conditions were attained within the 0.5-4.0 ug/L working range and at the 0.06 ug/L detection limit, which system was interfaced to the feedback circuits and was applied to human urine for diabetic-patient diagnosis. It can be used for ex-vivo flow control analysis, vascular flow detection and other medicinal assays. The equations of the patients’ urine are y=36.65x+12.13 and R²=0.987, those of the healthy person of y= 2.5x+10.9 and R²=0.928 (patients: 118 ug/L; healthy person: 12.34 ug/L).
