Suspended SU-8 structures for monolithic microfluidic channels

Monolithic integration of well-ordered nanoporous structures in the microfluidic channels for bioseparation.

Gel electrophoresis and capillary gel electrophoresis are widely used for the separation of biomolecules. With increasing demand in the miniaturized devices such as lab-on-a-chip, it is necessary to integrate such a separation component into a chip format. Here, we describe a simple approach to fabricate robust three-dimensional periodic porous nanostructures inside the microchannels for the se...

Monolithic SU-8 Microcavities for Efficient Fluorescence Collection

The fabrication of capped microstructures such as channels or cavities typically involves multiple production steps. In this work we demonstrate a fabrication procedure that enables the generation of capped monolithic microstructures of arbitrary geometry in one single exposure step. The presented method also enables the embedment of metal self-aligned surfaces for use as electrodes or mirrors....

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 ...
