Smart drug delivery refers to a targeted drug delivery or precision drug delivery system that allows drugs to be administered to a specific location in the body or at a specific time with enhanced precision and control. This approach has several advantages, including maximizing the therapeutic effects of a drug while minimizing side effects.This book presents various stimuli-responsive micro- and nanomaterials for pharmaceutical industries. This volume: Covers the global market perspective of micro- and nano-smart materials in pharmaceutical industries. Details various processing routes. Discusses mechanisms for target release. Addresses applications in oral drug delivery, anticancer agents, anti-tumor drug delivery, and drugs for management of infection. This reference work is written to support researchers in the fields of materials engineering and biotechnology with the goal of improving the diagnosis and treatment of disease and patient quality of life.
