A plastic microdevice is presented to perform ultrasonic particle micromanipulation in flowing suspensions. Sorting processes are carried out by the action of ultrasonic standing waves strategically established across the width of a chip with a microchannel, attached laterally to an ultrasonic actuator.
Parallel and sequential manipulation of trapping, labeling and content extraction of single cell was realized using a 2-D simple flow channels. The proposed system consists of main channels, cell trapping pockets, drain channels and single cell content collection channels. We fabricated prototypes having 16 cell trapping pockets and 512 cell trapping pockets. Sequential all single cell handling for...
Negative dielectrophoresis (n-DEP) have been used to manipulate microparticles with immunoreagents (antigens or antibodies) in a microfluidic channel, and applied to develop a rapid immunoassay system. A microfluidic device, with three-dimensional (3-D) microelectrodes fabricated on two substrates, was used to manipulate particle flow in the channel and to capture the particles in the caged area that...
Polymer microspheres are commonly used in microfluidic devices for biomedical applications. However, the presence of these particles can compromise the reliable operation of the microfluidic devices, as particles have been observed to deposit successively until they block a flow passage, which then leads to device failure. This paper presents investigations of the mechanics of particle deposition...
Suspended micro- and nanoscale polymer fibers were created using a novel technique which is performed at room temperature. This method involves drawing solvated PMMA into liquid filaments, which thin, via surface tension, as the solvent evaporates, subsequently yielding a solid fiber. The PMMA solution was drawn by two separate techniques: 1) using a stylus to extend a solution filament between two...
