Lab-on-a-Chip Integrates Microfluidics, Optical Traps
In a new type of “lab-on-a-chip” technology, particles in a microfluidic system are sorted by light.
Numerical simulation of the Cornell group’s trapping experiment. The optical waveguide propulsion is perpendicular to the direction of the pressure-driven flow in the channel.
Electric field profile of the quasi-transverse-magnetic mode for a water-clad SU-8 waveguide on a fused silica substrate. The waveguide’s height and width are 560 nm and 2.8 µm, respectively.
In a new type of “lab-on-a-chip” technology, particles in a microfluidic system are sorted by light. Optical transport adds another method of controlling movement through these tiny devices beyond pressure-driven flow.
