Polymer nanocomposites, a class of innovative materials formed by polymer matrixes and nanoscaled fillers (e.g., carbon-based nanomaterials, inorganic/semiconductor nanoparticles, metal/metal-oxide nanoparticles, polymeric nanostructures, etc.), display enhanced mechanical, optoelectrical, magnetic, catalytic, and bio-related characteristics, thereby finding a wide range of applications in the biomedical field. In particular, the concept of supramolecular chemistry has been introduced into polymer nanocomposites, which creates myriad "smart" biomedical materials with unique physicochemical properties and dynamic tunable structures in response to diverse external stimuli. This review aims to provide an overview of the chemical composition, morphological structures, biological functionalities, and reinforced performances of supramolecular polymer nanocomposites. Additionally, recent advances in biomedical applications such as therapeutic delivery, bioimaging, and tissue engineering are also discussed, especially their excellent properties leveraged in the development of multifunctional intelligent biomedical materials.
聚合物纳米复合材料是一类由聚合物基体和纳米级填料（如碳基纳米材料、无机/半导体纳米颗粒、金属/金属氧化物纳米颗粒、聚合物纳米结构等）形成的创新材料，具有增强的机械、光电、磁、催化和生物相关特性，因此在生物医学领域有广泛应用。特别是，超分子化学的概念已被引入聚合物纳米复合材料中，从而产生了无数具有独特物理化学性质和可响应各种外部刺激的动态可调结构的“智能”生物医学材料。本综述旨在概述超分子聚合物纳米复合材料的化学成分、形态结构、生物功能和增强性能。此外，还讨论了生物医学应用（如治疗递送、生物成像和组织工程）的最新进展，特别是它们在多功能智能生物医学材料开发中所利用的优异性能。
