Voltammetric enzyme dual sensors for simultaneous determination of free and total prostate specific antigen (fPSA and tPSA) are described. Alkaline Phosphatase (AP) and a mixture solution of 3-indoxyl phosphate and silver ions were used as the enzymatic label and substrate, respectively. 8A6 or 5G6 antibodies specific for free and total PSA, respectively, were immobilized on different screen-printed electrodes (SPEs)--screen-printed carbon electrodes, screen-printed gold electrodes and screen… CONTINUE READING
