Abstract

In this paper, two technologies (Photolithographic and Laser) and three designs of interdigitated electrodes (Simple IDT, Assymetric Branching IDT and Branching IDT) were compared for simple conductivity measurements of saline solutions (NaCl) and for enzymatic detection of protein (Bovine Serum Albumin). The results of both tests, showed that the Assymetric Branching IDT is the most sensitive in comparison to other electrodes, its sensitivity is 1.5 higher than that of simple IDT for conductivity measurements and 2.2 higher for protein detection. Moreover, the "laser" electrodes present a remarkable reproducibility in comparison to the "photolithographic" electrodes.
