Smart Polymers for Controlled Drug Delivery
Pages 24

Since the beginning of recorded history, natural polymers have been utilized by humans to pro­ mote health and healing. For example, early Egyptians used linen for suturing wounds. In the twentieth century, not long after the development of synthetic polymers, use of polymers in a broad range of biomedical applications has been the focus of many researchers and clinicians (1). The rapid advancement of biomedical research led to many creative applications for bio­ compatible polymers. As modern medicine discerns more mechanisms both of physiology and of pathophysiology, the approach to healing is to mimic or, if possible, recreate the physiology of healthy functioning.
