Abstract
We demonstrate theoretically and experimentally gradient-force induced, nanoparticle shockwaves forming in dense strongly scattering colloidal-suspensions. These light-induced directional `spear-shaped´ wavefronts allow concentrating and transporting large amounts of nanoparticles in local regions of a microfluidic channel.
