摘要: Polyurethanes (PUs) are synthesized by reaction of diisocyanates with polyols, resulting in the formation repeatable units carbamate (urethane) linkages. They often coupled other diols or diamines (chain extenders) to fine-tune their mechanical properties. PUs used day-to-day household items, for heavy engineering, sophisticated instruments, and also biomedical research. This chapter reviews applications context drug delivery. The is classified on basis different delivery systems that may be fabricated from such as nanoparticle systems, shape-memory system, stimulus-responsive covalently conjugated systems. have been around more than 75 years, still a lot offer meet demands newer
