Microfluidic devices made of UV-curable glue (NOA81) for fluorescence detection based applications

Nico de Rooij, Philip Wägli, Blaise Guélat

The UV-curable adhesive NOA81 (Norland Optical Adhesive) is a promising liquid photopolymer for low-cost microfluidic chip production. Different fabrication methods for NOA81 are suggested [1,2]. However, optical characterization for fluorescent based dete ...

A fixed-volume microfluidic mixer realized using multilayer PDMS technology

Martinus Gijs, Hüseyin Cumhur Tekin

We present leakage-free valves and an efficient fixed-volume mixer fabricated using a four-layer soft lithography technique in polydimethylsiloxane (PDMS). Mixing is achieved with a 95% efficiency in a few seconds by creating circular flow patterns inside ...

Micro-optics for multiple laser trapping in microfluidics

Fabrice Merenda

Optical trapping allows manipulating very small objects – varying from Angstöms to micron size particles – without physical contact by taking advantage of laser light. This technique, relying on light momentum transfer, allows manipulating biological matte ...

A compact optofluidic microscope

Demetri Psaltis

We demonstrate a novel optical imaging device that can be directly integrated into a microfluidic network, and therefore enables on-chip imaging in a microfluidic system. This micro imaging device, termed optofluidic microscope (OFM) is free of bulk optics ...
