Abstract

In this work the performance of a printed ThL laccase biocathode is studied utilizing different electrode substrates, compositions and enzyme activities. The results indicate that the performance of the manufactured biocathode can be optimized by selecting a suitable substrate material and increasing the enzyme and mediator loading. By varying the substrate material app. 40 % increase in the cell performance was achieved. In addition by adding ten times higher amount of enzyme and mediator increased the cell performance app. 20 %.
