Manufacturing of Lab-On-a-Chip devices : variation analysis of liquid delivery using blister packs
Components for on-chip storage and delivery of liquid reagent are necessary for many commercial applications of lab-on-a-chip technology. One such system uses a 'blister pack' that is pushed by an actuator. Over the course of product development, Daktari Diagnostics had completed nominal design of …

Microfabrication methods for the study of chemotaxis
… Numerical models were generated to investigate fluid flow in microchannels for given geometries. Through computational modeling and experimentally-driven iteration of the design, features of the chamber were determined and geometry was established. Prototypes of the system were fabricated using …
