Abstract

Responsive polymeric systems are considered to be smart materials, which are capable of altering the characteristics physically and/or chemically upon the exposure to several external stimuli, for example: pH, temperature, electrical fields, magnetic fields, light intensity, ultrasound, etc. Over the years, numerous responsive polymeric systems have been investigated for a diverse array of biomedical uses, e.g., drug delivery, gene delivery, cell encapsulation, tissue regenerations, smart coatings, biosensing, etc. Responsive polymeric systems have also been employed for targeted drug deliveries and triggered drug releasing of numerous drugs to competently enhance the therapeutic competence with the avoidance of side effects in the treatment of different deadly diseases including cancers. This chapter reviews the state-of-the art in responsive polymer-based systems for drug delivery applications.
