Rieske Iron–Sulfur Cluster Proteins From an Anaerobic Ammonium Oxidizer Suggest Unusual Energetics in Their Parent Rieske/Cytochrome b Complexes

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 4, Page 905-920, April 2026.
ABSTRACT Anaerobic ammonium‐oxidizing (anammox) bacteria employ a unique, hydrazine‐based pathway to obtain energy from nitrite and ammonium. These organisms possess distinct Rieske/cytochrome b complexes whose precise role in anammox metabolism remains unclear, but which have been proposed to include the generation of NAD(P)H.

Enhanced Microbial Sensing via Resazurin Reduction Catalyzed by Graphene Oxide, A Versatile Approach for Diagnostics and Electrochemical Applications

Environmental Toxicology, Volume 41, Issue 4, Page 223-232, April 2026.
ABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the

Electrochemical Assay of Human Islet Amyloid Polypeptide and Its Aggregation

Sensors, 2008
Square wave voltammetry is used in this work to detect human islet amyloid polypeptide (hIAPP) by using the oxidized signal of the tyrosine residue in hIAPP. A detection limit of 1×10-6 M for hIAPP has been obtained. A kinetic study of the aggregation

Adaptive Laboratory Evolution of Cupriavidus necator to Improve Energy Demand in Bioelectrochemical Cultivations

ChemElectroChem, Volume 13, Issue 5, March 2026.
This study highlights biological improvement through adaptive laboratory evolution of Cupriavidus necator H16 ΔPHB. Adapted strains tolerated up to 400 mM Na2SO4 showing better growth under salt stress. This enhanced robustness reduced cultivation energy demand in bioelectrochemical systems by ~ 11%, enabling more sustainable bioelectrochemical ...

Building Localized NADP(H) Recycling Circuits to Advance Enzyme Cascadetronics

Angewandte Chemie, Volume 137, Issue 10, March 3, 2025.
A consequence of the high catalytic activities and selectivities of many enzymes is that cascades enclosed within a mesoporous conducting material using NADP(H) and intermediates as internal current carriers display the almost instantaneous information‐transfer properties usually associated with electronic circuits.

Logic Circuits Featuring Organic Electrochemical Transistors: What is the Logic Behind OECTs in Logic?

Advanced Science, Volume 12, Issue 46, December 11, 2025.
For bioelectronic applications, organic electrochemical transistors (OECTs), with their mixed ionic and electronic conduction, will be invaluable for interfacing with living systems. This review examines the latest research, which has shifted towards integrating OECTs in logic circuits capable of transducing and processing bio‐signals.
