Sticking to the time and the place: Cell adhesion can be photocontrolled spatiotemporally on a photoresponsive culture dish functionalized with a caged cell-adhesion motif, namely a nitrobenzyl-substituted argine-glycine-aspartate peptide. Photolysis of the dish cleaves the nitrobenzyl group to produce the active peptide to which HeLa cells can adhere (see micrograph: left half, irradiated).
