Biocompatible polymers are a class of materials that are designed to interact with living tissue without causing harmful effects. These polymers have a wide range of applications in the biomedical field, including drug delivery, tissue engineering, and medical implants. Biocompatible polymers can be made from natural or synthetic materials, and they can be engineered to have specific properties such as biodegradability, mechanical strength, and surface chemistry. Some examples of biocompatible polymers include polyethylene glycol (PEG), polylactic acid (PLA), and polyurethane (PU). The development of biocompatible polymers has revolutionized the field of medicine and has enabled the creation of new treatments and therapies that were previously impossible.
