CHANNEL FOR TRAPPING PARTICLES TO BE FED TO SAID CHANNEL WITH A FLUID

摘要

The invention relates to a channel for trapping particles to be fed to said channel with a fluid, said channel having a bottom and opposite sidewalls, the sidewalls defining a width of the channel, said channel further comprising:
- a first channel part;
- a second channel part in fluid through flow connection with said first channel part and downstream of said first channel part;
- an elevated structure provided in said channel that divides said channel in said first channel part and said second channel part and for trapping particles in said first channel part;
- at least one flow gap provided by said elevated structure for providing said fluid through flow connection between the first channel part and the second channel part for allowing, in use, at least some fluid to flow past said elevated structure into said second channel part while trapping said particles in said first channel part;
wherein said elevated structure is substantially U-shaped and has a base extending substantially between the opposite sidewalls of the channel and two legs extending from the base in an upstream direction, wherein at least part of said U-shaped elevated structure defines at least part of a particle trapping area for trapping the particles to be fed to said channel. The invention further relates to a flow cell comprising such a channel. The invention also relates to an assembly comprising such a flow cell and a detection means. The invention also relates to a method for trapping particles in such a channel. And finally, the invention relates to a method for analyzing a sample using such an assembly.
