A gas breathing hydrogen/air biofuel cell comprising a redox polymer/hydrogenase-based bioanode

open access: yesNature Communications, 2018
Hydrogen is an attractive alternative fuel, but many hydrogen-conversion electrocatalysts contain expensive materials. Here the authors report a dual-gas breathing hydrogen/air biofuel cell comprised of a modified polymer/hydrogenase bioanode and a ...

Effect of bile pigments on the compromised gut barrier function in a rat model of bile duct ligation. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Studies have shown that the absence of bile in the gut lumen, either by bile duct ligation or bile diversion, induces mucosal injury. However, the mechanism remains elusive. In this study, the role of bile pigments in gut barrier function was

Freestanding biopellet electrodes based on carbon nanotubes and protein compression for direct and mediated bioelectrocatalysis

open access: yesElectrochemistry Communications, 2021
The fabrication of bioelectrocatalytic protein electrodes by the simple compression of carbon nanotube and protein powders was investigated using a series of proteins including bilirubin oxidase (BOx), bovine serum albumin (BSA), catalase, cytochrome C ...

Effect of bilirubin on cytochrome c oxidase activity of mitochondria from mouse brain and liver

open access: yesBMC Research Notes, 2010
Background The unbound, free concentration (Bf) of unconjugated bilirubin (UCB), and not the total UCB level, has been shown to correlate with bilirubin cytotoxicity, but the key molecular mechanisms accounting for the toxic effects of UCB are largely ...

Significance of Nano-Structures of Carbon Materials for Direct-Electron-Transfer-type Bioelectrocatalysis of Bilirubin Oxidase

open access: yesElectrochemistry, 2020
Three types of widely used carbon materials were examined as scaffolds for the direct-electron-transfer (DET)-type bioelectrocatalysis of bilirubin oxidase (BOD) as an electrocatalyst for a 4-electron reduction of oxygen (O2).

Photo-stimulated self-powered electrochemical system for DNA release

open access: yesSensors and Actuators Reports, 2021
The DNA-release activated by light in the self-powered bioelectronic system has been studied. The system was composed of two connected electrodes: one photo-active electrode was modified with photosynthetic thylakoid membranes and another electrode was ...
