Remote reversible control of swelling/contraction transition of a microgel is realized using azobenzene-containing surfactant. The azobenzene unit is switched between more hydrophilic cis (UV light) and more hydrophobic trans (blue light) state, which alters the surfactant's affinity to the microgel. The trans-surfactant binds to the gel, triggering its contraction, and the cis-surfactant unbinds, leading to microgel swelling.
