Abstract
The method, device, and system relate to particle analysis, and in particular, to a microfluidic device designed for trapping particles for analysis. Particles include beads and cells.
Claims15
A microfluidic particle analysis device comprising
- a microfluidics body,
- formed in said body, a microfluidics channel for receiving particles at an upstream region thereof,
- said channel having a deformable wall portion that defines a particle-capture region, and which is responsive to a change in fluid pressure applied thereto, to selectively vary the particle-flow dimensions of said capture region,
- wherein particles having a given size may be selectively retained in said capture region.
