Abstract

In this work, the use of medical adhesive tape-as a substrate to develop novel sensor architecture for the detection of hemoglobin (HB) has been investigated. The electrodes were fabricated based on the screen-printing method. The proposed electrode was characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, and cyclic voltammetry. The medical adhesive electrode showed excellent electrochemical behavior for dopamine, which was used for characterization and proof of concept. Also, the electrode was applied for HB electrochemical detection in the range of 1.0 to 10 mg mL(-1), with a detection limit of 0.7 mg mL(-1)by using differential pulse voltammetry. This sensor has shown resistance to mechanical stress, even when deformed based on its wearable functions, which is an exciting alternative for the development of low-cost electrochemical devices.
