<P>PROBLEM TO BE SOLVED: To provide a nanoscale fiber which is made of polysaccharides as a material and usable as a scaffold or a support of a cell tissue and as a part of a substrate for biological tissue culture and a biological material (an artificial valve, an artificial organ, an artificial blood vessel, a wound covering material, etc.) for the purpose of repairing, regenerating and treating substitute skin or a defective tissue as a medical material in the medical field, especially in regeneration medicine, has excellent supply of oxygen or nutrients and is expectable of efficient proliferation and differentiation of cells and to further provide a nonwoven thin film composed of the fiber and a formed product processed therewith. <P>SOLUTION: The nanoscale fiber which is made of the polysaccharides as a main raw material, obtained by a method for electrostatic spinning and characterized as having ≤500 nm diameter. The nanoscale fiber of the polysaccharides which is the fiber of a composite composition containing an additive other than the polysaccharides or fiber of the polysaccharides alone. The nanoscale fiber of the polysaccharides has 1-100 nm diameter. The nonwoven thin film is composed of the fiber and the nonwoven thin film is composed of an aggregate of the fiber and a microfiber having >500 nm diameter. The medical material comprises the fiber and the medical material comprises the nonwoven thin film. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
