贻贝的足丝可以分泌出贻贝黏附蛋白,使其在潮湿的海洋环境中也可以牢牢黏附在各种物体表面。 聚去甲肾上腺素 (PNE)是类似于贻贝足丝结构的仿生材料,具有制备工艺简单、生物相容性好、黏合性强、易于功能化、光热转换效率高等特点,它可以由去甲肾上腺素(NE)单体在弱碱性 pH 环境中自发聚集形成。 此外,NE 能够在绝大多数材质的基底上聚集成纳米尺度的 PNE 薄膜,产生亲水性强、化学性能稳定、生物相容性优良的仿生表界面。 近年来,基于 PNE 优异的物化性质构建多功能的纳米平台,并开始被用于组织工程、生物传感、电极优化、癌症治疗等应用领域。 这篇综述对近年来 PNE 的结构、性能和应用研究进行分类介绍、分析和总结,并对其存在的挑战和未来发展前景进行讨论和展望。 |

Abstract: |
Mussels can secrete adhesion proteins, which allow them to adhere firmly to various surfaces even in humid marine environments. Polynorepinephrine (PNE) is a mussel-inspired biomimetic material with many desirable properties, such as simple preparation process, good biocompatibility, strong adhesion, easy functionalization, and high efficiency in photothermal conversion. It can be formed by the selfassembly of norepinephrine (NE) monomers in weak pH environment. In addition, NE is able to aggregate and form nanoscale PNE film on most substrates, providing the bionic surfaces with strong hydrophilicity, chemical stability, and excellent biocompatibility. In recent years, the multifunctional nanoplatforms have been constructed based on the excellent physicochemical properties of PNE, with wide application in tissue engineering, biosensing, electrode optimization, cancer therapy, etc. This review focused on the fundamental structure, properties, and application of PNE, with a view to discussing the challenges and future of PNE research. |
