Smart polymers

Definition

Smart polymers are advanced materials that can respond to external stimuli such as temperature, pH, light, or electric fields, leading to reversible changes in their properties. These unique features allow them to be used in various applications, particularly in drug delivery systems, where their ability to control the release of therapeutic agents can improve treatment efficacy and reduce side effects.
