Catch and Release Method for Charged Particle Concentration

Introduction Cell separation in a microfluidic device can be difficult at times. One difficulty researchers face is the ability to capture and separate charged particles when carried in an aqueous solution. Technology description Our researchers have developed a microfluidic method and device to capture and separate charged cells in an aqueous solution. Business opportunity Some advantages of this new capture and separation method and device are: 1) it can be used with a large concentration of charged particles from a free flowing solution; 2) it can be used in a batch process using arbitrary sample sizes; 3) it has all of the advantages of a filtration procedure; and 4) it is able to achieve a high concentration and a high extraction factor. Stage of Development Our researchers have successfully manufactured a working prototype and have preliminary data. Intellectual property position The UW is currently reviewing this technology for worldwide patent protection.
