Near patient detection of viral infection represents a powerful approach for the control of emerging threats to global health. Moreover, the ability to identify individuals who have contracted the disease and developed antibodies that confer immunity is central to a return to normal daily activities. This review presents some of the recent advances in electrochemical sensors for the detection of viruses and their associated antibody profiles. Given the speed, portability, sensitivity and selectivity achieved using electrochemical detection, these sensor systems hold the promise of transformative change in clinical practice.

In the present work, we report the synthesis and evaluation of a graphite-supported bismuth film working electrode (BiFE) in the simultaneous quantification of Hg(II) and Pb(II) at ppb levels. The BiFE was synthesized in-situ by electrodeposition in 1 M HNO as the supporting electrolyte at -0.5 V potential.

The electrochemical CO reduction reaction (CORR) holds enormous potential as a carbon-neutral route to the sustainable production of fuels and platform chemicals. The durability for long-term operation is currently inadequate for commercialization, however, and the underlying deactivation process remains elusive. A fundamental understanding of the degradation mechanism of electrocatalysts, which can dictate the overall device performance, is needed.

Accurate and reliable quantification of disease-related biomolecules is essential for clinical diagnosis. In this study, a novel electrochemical approach is developed based on a target triggered DNA nanostructural switch from a hairpin dimer to a double-stranded wheel. During the process, electrochemical species get closer to the electrode interface, and the multiple intramolecular strand displacements are beneficial to low abundant target analysis.

In this study, we emphasize the importance of identifying Let-7a, a microRNA that is key in diagnosing and predicting lung cancer outcomes. Let-7a's function as a biomarker is essential, as it affects tumor suppression and controls cell differentiation and growth. We developed a novel device, an electrochemical biosensor based on Duplex Specific Nuclease (DSN), that is designed for the accurate detection of Let-7a.
