Current-Volt Biosensing “Cystatin C” on Carbon Nanowired Interdigitated Electrode Surface: A Clinical Marker Analysis for Bulged Aorta

Figure 3

Process of the capture probe “papain” immobilization on the carbon nanofiber-modified interdigitated electrode surface. (a) Voltages vs current responses for the immobilization process. Clear increment of current was noted after each immobilization. (b) The current level of the capture probe “papain” immobilization process. A higher increment of current was recorded after adding papain on the electrode.
