Sorting of particles such as cells is a critical process for many biomedical applications, and it is challenging to integrate it into an analytical microdevice. We report an effective and flexible dielectrophoresis (DEP)-based microfluidic device for continuous sorting of multiple particles in a microchannel. The particle sorter is composed of two components-a DEP focusing unit and a Movable DE...

Effective methods for manipulating, isolating and sorting cells and particles are essential for the development of microfluidic-based life science research and diagnostic platforms. We demonstrate an integrated optical platform for cell and particle sorting in microfluidic structures. Fluorescent-dyed particles are excited using an integrated optical waveguide network within micro-channels. A d...

This work presents continuous-flow particle sorting at low applied fields (as low as 30 V/cm) using electrodeless dielectrophoresis [2-7] in ridged polymeric microstructures. Particle manipulation and sorting is critical in the analysis of cellular systems and subpopulations, water monitoring, soil analysis, and colloidal synthesis. This technique is developed with a view toward sorting of cell...

Inertial microfluidics is a promising tool for many lab-on-a-chip applications. Particles in channel flows with Reynolds numbers above one undergo cross-streamline migration to a discrete set of equilibrium positions in square and rectangular channel cross sections. This effect has been used extensively for particle sorting and the analysis of particle properties. Using the lattice Boltzmann me...

The lack of personal particulate matter (PM) monitoring technique hinders the knowledge negative health impacts caused by inhaling PM. Acoustophoresis has a potential to produce miniature particle sorters that can be carried inside human’s breath zone. Micron particles manipulated Acoustic Radiation Force (ARF), but sub-micron hardly directed due Streaming Effect (ASE). purpose this study is ex...
