A novel monolithic enzymatic microreactor was prepared in the fused-silica capillary by in situ polymerization of acrylamide (AA), N-acryloxysuccinimide (NAS) and ethylene dimethacrylate (EDMA) in the presence of a binary porogenic mixture of dodecanol and cyclohexanol, which could offer very low back pressure, enabling the fast digestion of proteins. The performance of the monolithic microreac...

Photocatalytic microreactors have been utilized as rapid, versatile platforms for the characterization of photocatalysts.
