Provided is a method of focusing particles. The method includes: providing a suspension of the particles in a suspending medium; and flowing the suspension along a channel, such that the flowing suspension occupies a certain volume that has at least one cross-sectional dimension smaller than 100 mum. The suspending medium has such viscoelastic properties, that flowing the suspension in the channel directs at least some of the particles towards a focus region, enclosed in said certain volume. |
