One-step adsorption method used for preparing protein microcapsules

The invention relates to a one-step adsorption method used for preparing protein microcapsules, and belongs to the field of biomaterial. The one-step adsorption method is characterized in that: a polyphenol is adopted for doping of calcium carbonate micrometer particles, adsorption of protein is realized under mild conditions, crosslinking of the proteins adsorbed by the surfaces of the particlesis carried out, and at last calcium carbonate is removed so as to obtain the protein microcapsules. The advantages are that: the proteins used for preparing the protein microcapsules possess high universality; a plurality of times of assembling is not needed in preparation of the microcapsules; the one-step adsorption method is simple; preparation efficiency is high; conditions are mild; no impurity is introduced; the protein microcapsules possesses excellent biocompatibility and biodegradability, and is promising in medicine research and application prospect. 本发明涉及种步吸附法制备蛋白质微胶囊的方法，属于生物材料领域。其特点在于：利用多酚掺杂碳酸钙微米颗粒，在温和的条件下
