Abstract

We development a nanofluidic enzyme reactor exceeding the limitation of bulk enzyme reaction. The limit concentration of bulk trypsin solution is approximately 0.5 PM because self-digestion occurs over 0.5 PM solution, which complicates analysis of target proteins by digestion trypsin itself. Using extremely high surface/volume ration of nanospace, trypsin concentration, which indicates number of immobilized trypsin molecules on the nanochannel surface for liquid phase volume, exceed to bulk limit of concentration. As a result, 31 times higher concentration and 33 times faster enzyme reaction compared to bulk was realized. This reactor will be powerful tools which overcomes limitation in bulk and microfluidic method.
