Spatial control of discharging of tribocharges on polymers by (focused) light. a Polymer beads charged in the dye solutions (shown here, 40 poly(tetrafluoroethylene) (PTFE) beads in 1 × 10−5 M Coumarin 6 (C6) in dry hexane) can be individually discharged by targeting them with a handheld laser (404 nm). b A 1:1 electrostatic self-assembly of PTFE and poly(oxymethylene) (POM) beads29 in C6 solution (1 × 10−5 M, dry hexane) in a gently agitated petri dish can be disassembled after discharging of the beads upon UV illumination. c 2D and 3D assemblies of polymer beads can be “cut” by a laser at desired locations. (Here shown, 1:1 electrostatic self-assembly of PTFE and POM beads in C6 solution (1 × 10−5 M, dry hexane), see also Supplementary Movie 5)
