Drug delivery systems and pharmaceutical nanocarriers that respond to different types of stimuli, such as internal ones, intrinsic for the pathological area (changes in pH, temperature, redox condition, activity of certain enzymes), or external, artificially applied (magnetic field, ultrasound, various irradiations), represent an important and continuously growing area of research. Smart Phramaceutical Nanocarriers overviews the various stimuli used for drug release and delivery by smart pharmaceutical carriers and presents cutting-edge research and the newest data from the leading laboratories in each area.
