The response to temperature and glucose, high salt tolerance and self‐regulated drug delivery are simultaneously probable by applying a multifunctional microgel in a rational design by a colloid chemistry method. Such smart microgels were fabricated with thermoresponsiveN‐isopropylacrylamide, glucose‐sensitive (2‐phenylboronic esters‐1,3‐dioxane‐5‐ethyl)methyl acrylate (PBDEMA) and water‐soluble crosslinker poly(ethylene glycol) diacrylate through a precipitation emulsion method. These colloidal nanoparticles exhibited PBDEMA‐composition‐dependent responsive behavior with changing temperature and ionic strength. Amongst them, the microgel with 20.7 mol% PBDEMA with a narrow size distribution is suitable for diabetes treatment because it can adapt to the surrounding medium of different glucose concentrations over a clinically relevant range (0–2.0 mg mL−1), control the release of preloaded insulin and is highly stable under normal physiological conditions. Preliminary experiments suggest these highly stable microgels have the potential to be used for self‐regulated therapy and monitoring the response to treatment. © 2018 Society of Chemical Industry
