Smart polymers are attracting the researchers for development of novel drug delivery systems. Importance of smart polymers is rising day by day as these polymers undergo large reversible, physical or chemical changes in response to small changes in the environmental conditions such as pH, temperature, dual- stimuli, light and phase transition. Smart polymers are representing promising means for targeted drug delivery, enhanced drug delivery, gene therapy, actuator stimuli and protein folders. In the present paper, different types of smart polymers, along with their examples, mechanism of action and applications are reviewed.
