%X 二维材料的超薄原子层结构使其具有独特的力学性能、导热导电性以及巨大的比表面积，在能源存储、催化、传感和生物医学等领域引起了国内外学者的广泛关注。将二维材料与具有生物活性的生物大分子相结合可以为开发具有优异电学、力学和生物学功能的特种功能材料提供新的方法和途径。近年来，科研工作者针对这一方向展开了广泛的研究，取得了一系列重要的成果，使二维材料与生物大分子的结合与应用成为了新的研究热点。本文综述了近年来二维材料和生物大分子之间的相互作用及应用的研究进展，重点介绍了二维材料与生物大分子在分子水平上的相互作用机理，还总结了基于二维材料与生物大分子之间的相互作用在工程、疾病治疗和抗菌中的应用，并对其未来的研究趋势提出了展望。<br>With the rapid development of science and technology, various nanomaterials have continually emerged to meet human needs. As a newly emerging class of nanomaterials, two-dimensional (2D) materials have received wide attention recently in energy storage, catalysis, sensing and biomedicine due to their unique features such as good mechanical property, high specific surface area, excellent thermal and electrical conductivity. Biomacromolecules are the special organic molecules with various biological activities which exist extensively in every aspect of human life. When 2D materials meet biomacromolecules to display their own unique advantages, more opportunities and challenges have arisen for the exploitation and fabrication of novel nanomaterials with unique electrical, mechanical, biological properties and specific functions. In recent years, extensive research has been carried out with outstanding achievement thus the combination of 2D materials and biomacromolecules becomes a new hotspot. There were generally two binding interactions between 2D materials and biomacromolecules, namely non-covalent binding (electrostatic interaction, hydrophobic effect, π–π stacking, van der Waals interaction) and covalent binding (special chemical reactions between the functional groups of 2D materials and biomacromolecules). In addition, due to the excellent photothermal conversion performance, 2D materials could exhibit a non-contact interaction to biomacromolecules through the photo-thermal effect which has greatly broadened their applications. Up to now, numerous studies have clearly revealed the binding and effect mechanism and the research will be more focused on expanding the scope and application. Currently, the combination of 2D materials and biomacromolecules has widely involved in many cutting-edge applications such as flexible device, biosensor, smart skin, drug delivery, antibacterial, disease therapy and so on. Although a lot of progress has been made, several highlight open questions still need to be urgently addressed, such as the production cost of 2D materials, biological activity of biomacromolecules, stability and biocompatibility of 2D/biomacromolecule nanomaterials. This review summarizes the interactions between some typical 2D materials
