Abstract
A medicinal carrier is provided. The medicinal carrier comprises a first component, which is a biocompatible polymer with an amino group (—NH); a saccharide; and a second component which is a biocompatible material. The saccharide grafts to the first component via the amino group (—NH) of the first component, and the first component bonds to the second component via an ionic bond. The medicinal carrier can protect the medicine from gastric acid and swell or decompose to release the medicine under a specific pH condition, thus, showing a good applicability.
