A team lead by Sarah Perry designed a device capable of forming 20 nanoliter quantities of lipidic mesophase, a substance used to crystallize membrane proteins. Used in an array, such devices may prove to be a key in overcoming the crystallization bottleneck in determining the structures of these proteins.

A team lead by Benjamin Schudel has created an array of microfluidic wells for the screening of molecular binding events using very small sample quantities. Each 200 picoliter well contains its own biosensor, and incorporates a new type of valve which keeps the well sealed when at rest.

This interdisciplinary project resulted in the creation and validation of genetically encoded biosensor consisting of redox-sensitive polypeptide linkers between a FRET pair of fluorescent proteins. This biosensor allows real-time monitoring of the redox state of live cells for the study, e.g., of cell cycling and disease states.

The device designed by the team lead by Michael Toepke allows traditional flow-flash experiments to be done on a wider variety of timescales and with greatly reduced sample volume. When applied to the complex, multi-timescale study of protein dynamics it helps to bridge the knowledge gap between structure and function.

A team lead by Seon Kee Yoon performed an extensive study of methods for overcoming the formation of reactant-poor layers near the electrodes of laminar flow fuel cells. Application-specific methods were devised which are capable of improving efficiency and of improving power production by as much as 100%.

A team lead by Christian (no last name) designed microscale hydrogen steam reformers using ceramics which can withstand prolonged use at 800*C. Such reformers can be used for on-site production of H2 from liquid fuels for use in fuel cells, circumventing the need for storage of H2.

A new design by Ranga Jayashree and others takes advantage of diffusion kinetics to improve reaction rate in a laminar flow fuel cell. A gas-permeable electrode is rapidly supplied oxygen from flowing air rather than by an oxidant dissolved in the electrolyte stream, increasing fuel efficiency and power density several fold under optimized conditions.

A collaboration lead by Eric Choban investigated the electrolyte flexibility of membraneless micro fuel cells. Freed from the issue of membrane clogging by carbonate formation, laminar flow fuel cells can be run under alkaline conditions which result in better reaction kinetics (though slow diffusion can cause problems). The fuel and oxidant streams can even be at different pH's. The findings in this study showed that optimum conditions included an alkaline anode stream and acidic cathode stream.

Laminar flow focusing is used to take advantage of localized concentration gradients in order to drive reaction kinetics in the new bioreactor design by Seon Kee Yoon’s team. The reactor was shown to significantly improve cofactor regeneration rate, a key stumbling block in the controlled use of enzymes in manufacturing.

Michael Toepke has developed a new technique for creating tall device features by making use of an effect traditionally avoided in photolithography: diffracted light. Through the combined use of narrow mask features and a higher intensity of light than usually used, device features of varying heights up to 250 microns can be generated in SU-8 with a single exposure step. This approach eliminates the need for expensive and time-consuming machining and etching processes, or the tedious alignment of multiple layers.
