Polymeric microspheres is a new type of functional materials. At present the polymer microspheres cause of a growing number of academic interest. The application of polymer microspheres more and more widely, particularly in the biomedical field have a very good prospect. This paper reviews the polymeric microspheres of the carrier, biological active material, as well as the fixed polymer microspheres in the field of clinical medicine and medical applications, which introduces the magnetic polymer microspheres and fluorescent polymer microspheres. Polymer Microspheres are Macromonomer, seed polymerization, step-by-step heterogeneous pool, line-preparation methods, such as changes in law. Biomedical Polymer Microspheres are usually for the nuclear - Shell composite structure. At present there are commonly used polymer-polysaccharides, amino acid, ethyl cellulose, polyvinyl alcohol, polypropylene acid, polystyrene, and so on. If we add some magnetic material or functional groups will b
