- The paper focuses on the fact that, since the flow rate in parallel channels relies strongly on the channel width, the combination may lead to inaccurate results if errors in the fabrication process lead to an uneven distribution of channel widths. Parallel channel enzyme reactors were designed with channel widths distributed normally with different degrees of standard deviation. The reactors were then evaluated with regard to dispersion and to catalytic effect of the immobilised enzyme. It was shown that for lower concentrations the catalytic efficiency decreased significantly even for small variations in the distribution of channel widths and reactors with poor homogeneity in channel widths also diluted the sample more than the others.

- Two types of micro reactors were employed for enantioselective metal catalysed reactions. In the first type of reactor, an electroosmotic flow was used, whereas the second type of reactor used a pressure driven flow. The purpose of the study is to develop tools for rapid and efficient optimization of reactions, utilising minimum amounts of reagents.
