日本工业技术院四国工业技术试验所以海带或裙带菜等海藻中富含的多糖类藻朊酸为原料,在世界上首次试制医用纸获得成功。藻朊酸有较强的止血作用,可用来制作新型胶布等医疗用品。此外,藻朊酸对酶和微生物亦有很强的固定力,因此,也是生物反应器和生物传感器的高性能固定材料。据说,当榨去藻朊酸纤维中的水分时,纤维间便会相互紧紧地缠绕在一起。其制造方法就是利用了藻朊酸纤维的这一特性。首先从海藻中分离提取呈琼脂状的藻朊酸钠,再将藻朊酸钠通过较小的孔道挤入氯化钙溶液内,这时钠与钙发生离子交换,旋即形成藻朊酸钙细纤维,然后将纤维切短成三毫米左右,置于
Japan’s National Institute of Technology Industrial Technology Test Shikoku kelp or wakame seaweed rich in polysaccharide alginate as raw material, the world’s first trial of medical paper was successful. Alginate has a strong hemostatic effect, can be used to make new tape and other medical supplies. In addition, alginate also has a strong fixing force on enzymes and microorganisms, and is therefore also a high-performance fixing material for bioreactors and biosensors. It is said that when squeezing the water in the alginate fiber, the fibers are tightly intertwined with each other. Its manufacturing method is to use this feature of alginate fiber. First, the agar-like sodium alginate is separated and extracted from the seaweed, and the sodium alginate is squeezed into the calcium chloride solution through a smaller pore. At this time, sodium and calcium are ion-exchanged to form the calcium alginate fine Fiber, and then fiber cut into about three millimeters, placed
