Micelles self-assembled from thermoresponsive 2-hydroxy-3-butoxypropyl starches for drug delivery

► The thermoresponsive starch was synthesized by grafting hydrophobic groups. ► The LCST can be adjusted by varying the molar substitution of hydrophobic groups. ► The thermoresponsive starch would self-assemble into thermoresponsive micelles. ► The drug loading micelles showed thermoresponsive controlled release.
