Chitosan improves stability of carbon nanotube biocathodes for glucose biofuel cells

We demonstrate a novel combined chitosan-carbon-nanotube-enzyme biocathode with a greatly enhanced and stable long-term current density of -0.19 mA mL(-1). The fibrous microstructure of the electrode improves the performance of the biocathode by creating a protective microenvironment, preventing the...

Description
Summary:We demonstrate a novel combined chitosan-carbon-nanotube-enzyme biocathode with a greatly enhanced and stable long-term current density of -0.19 mA mL(-1). The fibrous microstructure of the electrode improves the performance of the biocathode by creating a protective microenvironment, preventing the loss of the electrocatalytic activity of the enzyme, and providing good oxygen diffusion.
