Selective and Sensitive Electrochemical DNA Biosensor for the Detection of Bacillus anthracis
International Journal of Electrochemical Science, 2016 The development of a selective and sensitive electrochemical DNA biosensor for detection of the pathogen Bacillus anthracis is proposed here. The technique is based on the characteristic cyclic voltammetry (CV) redox peaks and the very selective nature ...

ChemistryOpen, Volume 14, Issue 11, November 2025.This study presents a novel, rapid method for in situ functionalization of carbon electrodes using redox‐active form of the 6‐hydroxyflavone. The resulting multiwalled carbon nanotubes with redox‐active HFLA (MWCNT@HFLA‐Redox) electrode enables sensitive, selective detection of toxic phenylhydrazine, with excellent performance (limit of detection: 7 nM)

Current understanding of electroautotrophy and its relevance in astrobiology‐related research
mLife, Volume 4, Issue 5, Page 473-493, October 2025.Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Towards Scalable Electroenzymatic Hydrogen Production with [FeFe]‐Hydrogenase
ChemElectroChem, Volume 12, Issue 10, May 24, 2025.The [FeFe]‐hydrogenase metalloenzyme is a promising biocatalyst for sustainable electrocatalytic hydrogen (H2) production, however important issues need to be addressed before this can happen. For future biotechnologies to be realized, the [FeFe]‐hydrogenase enzyme should be more oxygen resistant, be produced in viable quantities and ultimately ...
