A drug carrier is provided, including an aqueous solution, a lactoferrin shell, graphenes, and a drug. The lactoferrin shell encloses the aqueous solution, and includes at least two hydrophilic layers and at least one hydrophobic layer. The two hydrophilic layers are the inner shell and the outer shell of the lactoferrin shell, and the hydrophobic layer is sandwiched by the two hydrophilic layers. The graphenes are dispersed in the hydrophobic layer, and the drug is in the aqueous solution and/or the hydrophobic layer.一種藥物載體包含水相溶液、乳鐵蛋白殼層、石墨烯以及藥物。乳鐵蛋白殼層包覆水相溶液，且包含至少兩層親水層以及至少一疏水層。兩層親水層為乳鐵蛋白殼層之內、外殼層，且疏水層夾於兩層親水層之間。石墨烯散佈於疏水層中，且藥物位於水相溶液及/或疏水層中。
