Abstract

Abstract : The photothermal effect has been exploited to promote directional fluid pumping and inert particle assembly using suspensions of either gold or titanium dioxide nanoparticles. In their Communication on page 2295 ff., A. Sen, A. C. Balazs, and co‐workers demonstrate the use of these directed flows to reversibly construct and move colloidal crystals. The cover picture is a schematic of gold nanoparticles being excited by UV light, which drives the assembly of larger micron‐sized particles.
