Absence of specificity in pharmacologically active agents is an obstacle to their effective use in biologic research and medicine. It follows that any approach enabling an agent to reach its target selectively and in a controlled fashion would contribute to the elimination of problems inherent in conventional methods. One such approach has been the development of a nontoxic and biodegradable carrier capable of containing a variety of substances of biologic interest that the carrier could, upon contact with a living entity, direct to the site of action and, subsequently, allow to perform their task. Ideally, there . . .
