This paper reports a multilayered, automated PDMS based microTAS for rapid, high-sensitivity and point-of-care insulin detection. Two generations of microTAS differing in their design complexity and insulin detection protocol were compared. The first generation microTAS includes one micropump, one micromixer and interdigitated electrodes to perform flow through impedance spectroscopy for insuli...

A low-voltage micropump with no moving parts and based on standard MEMS fabrication techniques has been developed. The pump has been characterized by pumping a variety of liquids, including de-ionized water, phosphate buffer saline, and aqueous solutions of sugars and alcohols as well as pure methanol, with typical pumping speeds of a few hundred micrometer per second. The small power/voltage r...

Archimedes micro-screws have been fabricated by three-dimensional two-photon polymerization using a Nd:YAG Q-switched microchip laser at 532nm. Due to their small sizes they can be easily manipulated, and made to rotate using low power optical tweezers. Rotation rates up to 40 Hz are obtained with a laser power of 200 mW, i.e. 0.2 Hz/mW. A photo-driven micropump action in a microfluidic channel...
