This article uses collagen and chitosan as raw materials,and uses the pH response of chitosan to prepare a composite microsphere without an additive.The content of collagen in the composite microsphere is determined by Sirius red staining method and hydroxyticine.In addition,the appearance,particle size,thermal stability,and water holding performance of the microsphere have been systematized.By using gingerin as an analog drug,the performance of the microspheres is explored.
