The present invention provides a method for preparing a drug composition, which includes steps of dispersing an amphiphilic chitosan derivative, at least a hydrophobic drug, and at least a hydrophilic drug into a solvent to form a mixture solution, and the pH value of the mixture solution is adjusted to a range without precipitating the hydrophilic drug(s) and the hydrophobic drug(s), wherein the amphiphilic chitosan derivative is modified by a plurality of hydrophilic group(s) and a plurality of hydrophobic group(s); and after stirring the mixture solution for at least 12 hours, receiving the drug composition when the pH value of the mixture solution is between pH 6 to 7. The hydrophilic drug(s) and the hydrophobic drug(s) are encapsulated simultaneously by one-pot synthesis, and the protein could be modified by one-pot synthesis to provide a drug composition with multiple functions.

A nanocomposite, a preparation method thereof and a method for treating cancer using the same are provided. The preparation method includes: mixing a first solution including an amphiphilic chitosan and a second solution including anti-cancer components, wherein the anti-cancer components includes gemcitabine, curcumin, the derivatives and combinations thereof; forming a nanoparticle encapsulating the anti-cancer component by a self-assembling process of the amphiphilic chitosan, and binding the nanoparticle with a targeting molecule having specificity to a cancer so as to obtain a nanocomposite. When dissolving the nanocomposite of the present invention after drying into water phase, the nanocomposite still has the same morphology and characteristic before it is dried, so it is convenient for storage and delivery. Additionally, the preferable ratio of gemcitabine and demethoxycurcumin will bring a synergistic effect on cancer therapy.

A self-assembled nanostructure including an amphiphilic chitosan and a contrast agent compound is provided. The contrast agent compound is grafted to the amphiphilic chitosan. The chemical bonding between the amphiphilic chitosan and the contrast agent compound has a synergistic effect to further improve the contrasting ability of the contrast agent compound.
