International status:- Over the past 20 years, the polymer and ailed industries have focused on synthetic Since their appearance in the literature, a wide range of degradable and non-degradable polymers have been demonstrated in drug delivery devices. Their unique ability to respond and adjust to the slightest environmental changes, including change in temperature, humidity, pH levels, and the intensity of light is why smart polymers are also known as stimuli-responsive polymers. This review includes various polymers used in pharmaceutics based on their applications. Polymer science: preparation and uses of polymers. 1. These materials have been intensively studied over the years for a diverse range of applications, e.g., for on-demand drug delivery, tissue generation/repair, biosensing, smart coatings, and artificial muscles. Ideal dendritic polymers … In recent years there has been an increase in interest in biodegradable polymers. There is a vast number of publications available on this topic, therefore only a selection of examples will be discussed. Nanoscale formulations such as liposomes, polymeric micelles, complexes, and nanofibers attracted special attention during the last decade. Key to the widespread application of smart polymers in drug delivery is understanding the mechanistic interplay, as well as consequence, of the presence of these macromolecules within living systems. Responsive polymer-based materials are capable of altering their chemical and/or physical properties upon exposure to external stimuli.
