Abstract
A 96 channel printhead for simultaneous delivery of 96 different biochemical substances in nanoliter quantities was built and tested. The printhead consists of two Pyrex layers that sandwich a Silicon wafer. The silicon was structured using Deep Reactive Ion Etching (DRIE). Critical points in the fabrication were identified and solutions presented. The final result is a printhead that works for a broad range of liquids and enables a far higher throughput in the production of biochips/microarrays as compared to currently available systems.
