20100170798 | Fabrication and use of semipermeable membranes and gels for the control of electrolysis - A microfluidic device and method is disclosed having one or more membranes for the control of electrolysis. In one embodiment, a microfluidic device is disclosed that includes body with first channel and second channels separated by a gel layer. A first electrode positioned in the first channel and a second electrode positioned in the second channel wherein a potential applied to the first and second electrodes passes electrons from the first channel to the second channel through the gel layer. In another embodiment, a microfluidic device includes a body having a surface with a channel separating two first reservoirs. One or more membranes are positioned on the surface covering a portion of the channel and a blank is positioned covering the channel and the one or more membranes. A second reservoir through the blank is in contact with the membrane, each second reservoir in communication with the channel via the membrane. A first electrode is positioned in the first reservoir and a second electrode is positioned in the second reservoir wherein a potential applied to the first and second electrodes passes electrons from the first channel to the second channel through the membranes. | 07-08-2010 |
20120228142 | FABRICATION AND USE OF SEMIPERMEABLE MEMBRANES AND GELS FOR THE CONTROL OF ELECTROLYSIS - Microfluidic devices having one or more membranes and methods of use for the microfluidic devices are disclosed. In one embodiment, a microfluidic device is disclosed that includes a body with first fluid passage and a membrane located between a first reservoir and the first fluid passage. A first electrode is in electrical communication with the first reservoir and a second electrode is in electrical communication with the first fluid passage. A potential applied across the first and second electrodes is capable of passing charged molecules through the membrane. | 09-13-2012 |

20120065329 | SYNTHESIS OF STABLE ELASTOMERIC NEGATIVE ACOUSTIC CONTRAST PARTICLES - We describe methods for synthesis and formulations of stable elastomeric negative acoustic contrast particles with controllable compressibility and density. These elastomeric negative acoustic contrast particles have a density/compressibility ratio that is less than that of water and therefore exhibit negative acoustic contrast under acoustic radiation exposure. This negative acoustic contrast allows our elastomeric negative acoustic contrast particles to be acoustically manipulated (e.g. separated) differently from other components (e.g. cells) within an aqueous solution. This disclosure also describes methods for biofunctionalization of the elastomeric negative acoustic contrast particles and as an example their use as platforms for bioassays. Potential applications of these elastomeric negative acoustic contrast particles include sensitive bioassays based on acoustic flow cytometry and other types of techniques that utilize acoustic fields, including ultrasound imaging and ultrasound triggered drug delivery. | 03-15-2012 |
