text: Nanocomposite hydrogels are observed to be temperature sensitive and will change temperature when their surrounding is altered. Inorganic salts, when absorbed, will result in changing the hydrogels to a lower temperature whereas cat-ionic surfactant will shift the temperature the other way. The temperature of these hydrogels are around 40 degrees Celsius, making it a possible candidate for use as biomaterial. The stimulus-sensitivity of hydrogels allow for a responsive release system where the hydrogels can be designed to deliver the drug in response to changes in condition of the body.
