Research Abstract |
Gel-materials, such as gelatin, collagen, and fibrinogen, derived from animals and humans, have been used widely in medical applications, although the materials include the possibilities of the contagions of a virus and an allergic material. We recently discovered that a novel carbohydrate polymer having a specific structure formed a new class of gel-material. Depending on the formulation and preparation method, materials ranging from viscous liquids, soft gels, and tough films can be obtained with widely varying gel formation kinetics. Since the starting materials are classified as biocompatible and biodegradable, this new class of gels has many potential medical applications, such as hemostatic, adhesive, and coating agents. Carbohydrate polymers having a specific structure can be synthesized from naturally occurring sugars or compounds microwave-decomposed from polysaccharide. The novel carbohydrate polymers have characteristics as follows ; 1)basic materials for medical applications at a reasonable cost, 2)easy control of the chemical and physical properties, 3)biocompatible and biodegradable materials. The reaction of the carbohydrate polymer with a gelling agent immediately forms the gel-materials, which offers several advantages over conventional gel preparations, including the use of non-contagion materials and short preparation times. The gel-materials are a versatile new class of biomaterials that hold promise for a wide variety of medical applications.
