Application Research of Sodium Alginate in Medical Engineering / 医疗卫生装备

The nature and preparation of sodium alginate are introduced and its medical applications are reviewed in fields such as medical carrier,gel microspheres,sustained-release materials,surgical wound repairing materials,and so on.Besides,its development prospects are described.It is an inevitable trend that sodium alginate is used in the development of controlled-release reagent.There are also important applications in the partial treatment of ear disease and artificial cartilage for sodium alginate,but the strength and toughness of alginate hydrogel limits its wider application.
