“…In some polymers, alteration of a property such as color, conformation, solubility, etc., may be a response to being subjected to certain external stimuli, which may include, among others, temperature [8,31], light [32,33], electric or magnetic fields [17,34], and pH [31,35]. Such polymers are called smart polymers and they can be applied in many areas, for example, in filtration [36,37], cell growth/detachment [38,39], and sensors [33,40], as well as those already mentioned above (drug delivery, tissue engineering scaffolds, wound dressing, and biomedicine).…”
