Reversible speed control of one-stimulus-double-response, temperature-sensitive asymmetric hydrogel micromotors

Chem Commun (Camb). 2022 Sep 15;58(74):10333-10336. doi: 10.1039/d2cc02854a.

Abstract

Soft, one-stimulus-double-response, thermo-sensitive, PNIPAm-based microgels are designed for controlled autonomous motion under stimuli. At higher temperature, the motors with physically encapsulated catalase move faster, while motors in which catalase is chemically linked to PNIPAm ceased moving. The phenomenon is reversible over multiple cycles of temperature.
