Abstract:

Recently, the unique and novel structure of hollow materials has become a hot spot in the research of synthetic chemistry and material chemistry, especially its high surface-volume-ratio, low density and large cavities, and it is also an excellent choice of drug delivery carrier. Through the precise selection and modification of hollow materials, the hollow materials can be endowed with unique stimulus response behavior, thus realizing the intelligent design of hollow materials and the controlled release of drugs. There are two strategies for constructing smart hollow carriers: (1) utilizing hollow materials as carriers that can respond to physical or chemical stimuli; (2) modifying functional molecules on the surface of hollow carriers to achieve specific “on-off” switch under stimulation. Its core lies in the precise regulation of molecular composition and configuration. From this perspective, we detail the construction connotation of gatekeepers for controlled drug release. This review begins with an introduction to the development history of hollow carriers, followed by a brief discussion on the rules of molecules released from hollow structures. The use of hollow structures for the construction of intelligent responsive drug carriers is then showcased, including roles of the hollow structure, different gating strategies, controlled release mechanisms, and their potential progress in application. This paper concludes with some perspectives on future directions for hollow structured carriers.

Key words: Hollow structure, Nano-micro structure, Stimulation response, Drug delivery carrier
