Paper Abstract

Micro-scale biochemical reactors have been developed from a polydimethylsiloxane/enzyme (PDMS-E)biopolymer. Micro-reactor channels 125 micrometers in depth, 500 micrometers wide by 50 centimeters long contain fixed triangular features for enhanced fluid mixing. All channel features are composed of the same PDMS-E material. Conversions of urea by urease enzyme of up to 70% have been obtained at an overall flowrate of 0.4 mL/min. Additional PDMS-E biopolymer systems containing amyloglucosidase (for converting starch to glucose) have demonstrated enzymatic activity.
