Smart SU-8 pillars implemented in a microfluidic bioreactor for continuous measurement of glucose

SU-8 free-standing microfluidic probes

We present a process for fabrication of free-standing SU-8 probes, with a dry, mechanical release of the final micro-devices. The process utilizes the thermal release tape, a commonly used cleanroom material, for facile heat-release from the sacrificial layer. For characterization of the SU-8 microfluidic probes, two liquid interfaces were designed: a disposable interface with integrated wells ...

Fabrication of Su-8 Microstructures for Analytical Microfluidic Applications

A superhydrophobic chip based on SU-8 photoresist pillars suspended on a silicon nitride membrane.

We developed a new generation of superhydrophobic chips optimized for probing ultrasmall sample quantities by X-ray scattering and fluorescence techniques. The chips are based on thin Si3N4 membranes with a tailored pattern of SU-8 photoresist pillars. Indeed, aqueous solution droplets can be evaporated and concentrated at predefined positions using a non-periodic pillar pattern. We demonstrate...

Pillars of a Smart, Safe Operating Room

Major gains in patient safety can be achieved through development of innovative approaches to the care of surgical patients. Investigators and clinicians have conceived an “operating room of the future” (ORF) that epitomizes those current and future enhancements that can contribute to patient safety in the operative environment. In this article, we explore these enhancements in the context of t...

Measurement of enzyme kinetics using a continuous-flow microfluidic system.

This paper describes a microanalytical method for determining enzyme kinetics using a continuous-flow microfluidic system. The analysis is carried out by immobilizing the enzyme on microbeads, packing the microbeads into a chip-based microreactor (volume approximately 1.0 nL), and flowing the substrate over the packed bed. Data were analyzed using the Lilly-Hornby equation and compared to value...
