  "id": "MLC-T-CHM-010271",
  "term": "Responsive gel",
  "field": "Chemistry",
  "definition": "A gel that undergoes a reversible, discrete volume change or a sol-gel transition in response to a small change in an external environmental condition. These stimuli can include temperature, pH, ionic strength, light, or an electric field. The volume phase transition temperature is a specific temperature at which certain thermoresponsive gels, like poly(N-isopropylacrylamide), exhibit a dramatic collapse or swelling.",
