PURPOSE: A method for storing hydrogel for a bio-sensor or drug delivery system is provided to improve chemical and physical characteristics without changing activation of enzyme. CONSTITUTION: Hydrogel containing poly ethylene oxide, poly acrylic acid, poly vinyl alcohol, poly acryl amido methyl propane sulfonate, poly methylene glycol, chitosan, or glucose oxidase is vacuum-dried at 100 deg. or lower. The dried hydrogel is kept in a desiccator for a predetermined period. Then, the dried hydrogel is expanded in a PBS(Phosphate Buffer Saline) solution. The expanded hydrogel is used as electrolyte of a bio-sensor and a drug delivery system. |
