<p>A method comprises introducing a fluid carrying mobile elements, such as particles (24), into a fluidic device. Simultaneously a mobile element receiving fluid and one or more further fluids are also introduced into the fluidic device. The fluids are passed through a chamber (12) in respective, parallel fluid streams (32, 34, 36, 38, 40). The fluid streams are arranged such that each fluid stream contacts at least another one of the fluid streams in the chamber (12). The dimensions of the chamber are such that the fluid streams undergo laminar flow and remain generally distinct from one another. A force is applied to the mobile elements (24) which causes the mobile elements to leave the fluid stream (32) of the mobile element carrying fluid, pass through the fluid stream(s) (34, 36, 38) of the further fluid(s) and enter into the fluid stream (40) of the mobile element receiving fluid. As the mobile elements pass through the fluid streams reactions can take place between species bound to the mobile elements and species carried in the fluid streams.</p> |
