An Overview and Current Challenges in Respect to Screen-Printed Electrochemical Electrodes Employability as Disposable Biosensors

Screen-printed electrodes (SPE) are the core of disposable electrochemical biosensors with a promising role in the electroanalytical experiments in biomedicine (analyte detection-protein, viruses, enzyme; diseases monitoring; biomarkers identification, etc.), providing both quantitative and qualitative information on bio-electrochemical reactions occurring at electrode surface. SPEs are of critical importance in development of portable, low-weight, miniaturized, and effective devices for biological fluid characterization for in-situ experiments. In spite of SPEs multiple advantages, such as their low cost, ease of use, and simple setup, their sensitivity and selectivity are common technological drawbacks.

The geometric parameters related to the electrodes’ design and the relationships between them might be a solution in addressing the sensitivity and selectivity issue raised. The herein paper is presenting a collection of data as a result of an in-depth analysis of experimental work reported by scientists in the recent (2019-2024) literature of the biomedical field.
