Patent Images
1. A substantially sealed, disposable cartridge for a MEMS particle sorting system, comprising:
- at least one microfabricated particle sorting structure formed on a substrate and installed in the substantially sealed, disposable cartridge;
a quantity of biocompatible material with a plurality of fluid reservoirs disposed therein, with one or more fluidic passageways connecting the fluid reservoirs to the MEMS particle sorting systema flexible gasket covering the reservoirs, wherein a plurality of holes formed in the gasket allows a fluid flow to between at least one of the reservoirs and the microfabricated particle sorting structure.

Abstract
A disposable cartridge is described which is compatible with a MEMS particle sorting device. The disposable cartridge may include passageways which connect fluid reservoirs in the cartridge with corresponding microfluidic passageways on the MEMS chip. A flexible gasket may prevent leakages and allow the fluid to cross the gasket barrier through a plurality of holes in the gasket. Vents and septums may also be included to allow air to escape and fluids to be inserted by hypodermic needle. A MEMS-based particle sorting system using the disposable cartridge is also described.
