Extracellular Bacterial Production of DNA Hydrogels–Toward Engineered Living Materials

Small, Volume 21, Issue 19, May 12, 2025.
The polymerase phi29‐ST, immobilized via SpyCatcher surface anchors on the exoelectrogenic bacterium S. oneidensis, enables the formation of DNA hydrogel materials in direct proximity to living cells. This results in a robust biofilm that enhances the current generation.

Analytical Bioelectrochemistry [PDF]

, 1985
Among the various analytical methods using biochemistry or physiochemistry bioelectrochemistry is one of the most active and rapidly developing fields. It is indeed rarely necessary to add any chemical in the sample, thus allowing direct in vivo application of these methods, and their selectivity and sensitivity is often sufficient to avoid any ...

Electrochemically Induced Nanoscale Stirring Boosts Functional Immobilization of Flavocytochrome P450 BM3 on Nanoporous Gold Electrodes

Small Methods, Volume 9, Issue 3, March 20, 2025.
A flexible‐modular approach for enzyme immobilization on nanoporous gold (npAu). A cationic protein module for directed binding is fused to the enzyme. The surface is modified with self‐assembled monolayer. Surface charge is modulated electrochemically. Thereby induced nanoscale stirring in the porous network strongly enhances yield and speed of enzyme

Defying Gravity to Enhance Power Output and Conversion Efficiency in a Vertically Oriented Four-Electrode Microfluidic Microbial Fuel Cell

Micromachines
High power output and high conversion efficiency are crucial parameters for microbial fuel cells (MFCs). In our previous work, we worked with microfluidic MFCs to study fundamentals related to the power density of the MFCs, but nutrient consumption was ...
