The use of a two‐photon [2+2] cycloaddition of maleimide groups to structure surfaces, hydrogels, and add modifications with sub‐micrometer precision is reported by M. Schlierf and co‐workers in article 1603327. Complex 3D structures of arbitrary shape can be embedded with two‐photon [2+2] cycloadditions in hydrogels, as illustrated here by a nested ball of fluorophores within a bulk hydrogel based on poly(ethylene glycol) (PEG). The frontispiece artwork was designed by Andreas Hartmann and Philip Gröger.
