This paper presents the fabrication of a microchemical chip for the detection of fluorescence species in microfluidics. The microfluidic network is wet-etched in a Borofloat 33 (Pyrex) glass wafer and sealed by means of a second wafer. Unlike other similar ...
We present a new approach for contactless conductivity detection for microchip-based capillary electrophoresis (CE). The detector integrates easily with well-known microfabrication techniques for glass-based microfluidic devices. Platinum electrodes are st ...
A set of new technologies to fabricate microchannels using photosensitive polymer materials is presented. They are based on the use of polymers, hereafter called photopolymers, that are cured with UV light under a mask exposure. The basic material is ail e ...
A new, versatile architecture is presented for microfluidic devices made entirely from glass, for use with reagents which would prove highly corrosive for silicon. Chips consist of three layers of glass wafers bonded together by fusion bonding. On the insi ...
We describe the microfabrication and use of elastomeric and rigid two-level microfluidic networks (μFNs), made of poly(dimethylsiloxane) (PDMS) or Si, for patterning surfaces. The first level corresponds to microchannels and the second to via holes through ...
Within the overall objective of developing a low dead volume technology for basic microfluidic valving, shunting and switching functionalities, the use of microbubbles is proposed. As a case study, a normally-closed, bubble-based microvalve design is prese ...
