Temperature-sensitive nanomaterials typically work through mechanisms such as phase transitions, changes in molecular structure, or variations in surface energy. For instance, certain polymers exhibit a lower critical solution temperature (LCST), where they undergo a phase transition from soluble to insoluble at a specific temperature. This property can be exploited in drug delivery systems to release drugs at the target site when the temperature rises to the LCST. Similarly, some metal nanoparticles change their electrical resistance with temperature, making them useful for temperature sensors.
