Matching the scale of microfluidic flow systems with that of microelectronic chips for realizing monolithically integrated systems still needs to be accomplished. However, this is appealing only if such re-scaling does not compromise the fluidic throughput ...
Extremely sensitive protein detection is crucial for early diagnosis and monitoring of diseases. Present day’s limit of detection for an antibody-antigen recognition-based immunoassay in serum without having to use special target antigen amplification tech ...
An a priori prediction of multiphase flow pattern in micro-capillaries or microstructured reactors (MSR) is required for their rational design. The state-of-the-art numerical models require huge computational efforts. In the present work, an analytical mod ...
The term of optofluidics defines an emergent research field that combines microfluidics and optics. In many lab-on-a-chip applications, these two technologies are used in combining the microfluidics for sample delivery and optics for sensing and controllin ...
Microfluidic structures in poly(dimethylsiloxane) (PDMS) are usually fabricated by optically patterning a resist and subsequently transferring this pattern to PDMS. Such microsystems suffer from reduced resolution, which in turn inhibit the manipulation of ...

We present a novel optofluidic differential method for carrying out absorbance spectroscopy of subnanolitre volumes of liquid samples on a microfluidic chip. Due to the reduction of liquid volume, the absorbance detection in microfluidics is often hindered ...
We present a novel image-based method to measure the on-chip microfluidic pressure and flow rate simultaneously by using the integrated optofluidic membrane interferometers (OMIs). The device was constructed with two layers of structured polydimethylsiloxa ...
We presented a pneumatically tunable 2 x 2 optofluidic switch for on-chip light routing that was controlled by compressed air. The device was fabricated with an optically clear elastomer-polydimethylsiloxane ( PDMS)-by soft-lithography. The optical switchi ...
We introduce for the first time the implementation of optofluidic lock-in spectroscopy of sub-nanoliter analyte on a microfluidic chip. Two methods, spatial modulation and pneumatic modulation with integrated optofluidic modulator, were demonstrated. (C) 2 ...

SU-8 photoresist is commonly used in the field of microfabrication as structural material or for molding of microfluidic devices. One major limitation, however, is the difficulty to process partially freestanding SU-8 structures or monolithic closed caviti ...
