Reversible biomolecular patterning in hydrogels can direct cell function in a user-defined manner. In their Communication on page 1816 ff., K. S. Anseth and C. A DeForest report 4D spatiotemporal control over the presentation of bioligands by using a thiol–ene photoconjugation reaction, which is initiated by visible light, combined with the photocleavage of an o-nitrobenzyl ether, which is controlled by UV light. This method allows cell functions to be probed dynamically.
