We have carried out investigations geared toward the fundamental understanding of the transport behavior in planar microfluidic membraneless fuel cells with the intent of locally enhancing mass transport, while maintaining laminar flow between fuel and oxidant streams. In order to accomplish this, we have employed staggered herringbone micromixers which were generated using microfabrication tec...

We report fabrication of a microneedle-based three-electrode integrated electrochemical sensor and in-vitro characterization of this sensor for glucose sensing applications. A piece of silicon was sequentially dry and wet etched to form a 15 × 15 array of tall (approximately 380 µm) sharp silicon microneedles. Iron catalyst was deposited through a SU-8 shadow mask to form the working electrode ...

A cross-channel geometry was studied to perform quantitative electrolysis of circulating droplets without influence the counter electrode reaction on droplet content. In microdevices, is located in a secondary microchannel prevent any contact with during detection. The electrochemical performance assessed both theoretically and experimentally based properties mass transport above working electr...

Ventricular defibrillation by electric counter shock is the definitive treatment for cardiac arrest due to ventricular fibrillation (VF). Ventricular defibrillation is the fundamental cornerstone to a successful outcome. As most deaths from VF occur out of hospital, often in patients without pre-existent recognised cardiac disease, the major public health issue remains the widespread applicatio...

A glass capillary ultramicroelectrode (tip diameter approximately 1.2 microm) having an electrokinetic sampling ability is described. It is composed of a pulled glass capillary filled with an inner solution and three internal electrodes (Pt working and counter electrodes and an Ag/AgCl reference electrode). The voltammetric response of the capillary electrode is based on electrokinetic transpor...
