PROBLEM TO BE SOLVED: To provide a method for forming a new biological scaffold, meeting requirements of rapid production, energy saving and a low price to overcome the defects of a conventional method. SOLUTION: Different macromolecular materials or different kinds of immobilization agents according to the requirement of application are provided to carry out an immobilization step under a low-temperature condition. The method comprises a dissolving step, a temperature-regulating step, a freezing step and the immobilization step. The immobilization step further includes one of a solid-liquid exchanging step, an acid and alkali-neutralizing step, and a gelatinizing step. COPYRIGHT: (C)2005,JPO&NCIPI
