Abstract : A new family of sophisticated materials called as "smart polymers," or "stimuli-responsive polymers," show notable changes in their chemical or physical characteristics in response to external environmental stimuli. This project offers a thorough review of smart polymers, starting with an introduction to their basic properties and moving through their categorisation according to various stimuli. The study examines three main types of stimuli: biological (such as enzymes and biomolecules), physical (such as temperature, light, and electric or magnetic fields), and chemical (such as pH and ionic strength). The project goes on to describe the benefits of smart polymers, such as their high sensitivity, biocompatibility, and potential for targeted and controlled applications, as well as their drawbacks, which include high production costs, difficult synthesis procedures, and stability issues. The relevance of smart polymers in site-specific and controlled drug delivery systems, which can greatly enhance treatment outcomes, is highlighted in a thorough explanation of the drug release mechanism. To further highlight the practical importance of smart polymers, examples of widely utilised smart polymers are looked at. A review of the various uses of smart polymers in domains like biomedical engineering, medication transport, tissue engineering, sensors, and environmental systems rounds out the project. All things considered, smart polymers are a quickly developing topic with enormous potential to transform contemporary science and technology due to their versatile and adaptable characteristics.

Keywords : Drug Delivery Systems, Advanced Materials, Biocompatibility, Smart Polymers, Stimuli-Responsive Materials, Chemical, Physical, and Biological Stimuli, 3D Printing, and Polymer Applications.
