In contrast to conventional particles characterized by isotropic surfaces, Janus particles possess anisotropic surfaces, resulting in unique physicochemical properties and functional attributes. In recent times, there has been a surge in interest regarding the synthesis of Janus particles using biological macromolecules. Various synthesis techniques have been developed for the fabrication of Janus materials derived from biomass. These methods include electrospinning, freeze-drying, secondary casting film formation, self-assembly technology, and other approaches. In the realm of Janus composite materials, those derived from biomass have found extensive applications in diverse domains including oil-water separation, sensors, photocatalysis, and medical materials. This article provides a systematic introduction to the classification of Janus materials, with a specific focus on various types of biomass-based Janus materials (mainly cellulose-based Janus materials, lignin-based Janus materials and protein-based Janus materials) and the methods used for their preparation. This work will not only deepen the understanding of biomass-based Janus materials, but also contribute to the development of new methods for designing biomass-based Janus structures to optimize biomass utilization.
与各向同性表面为特征的传统粒子不同，Janus 粒子具有各向异性表面，从而具有独特的物理化学性质和功能属性。最近，人们对使用生物大分子合成 Janus 粒子产生了浓厚的兴趣。已经开发了各种合成技术来制造源自生物质的 Janus 材料。这些方法包括静电纺丝、冷冻干燥、二次铸膜形成、自组装技术等。在 Janus 复合材料领域，源自生物质的 Janus 复合材料已在包括油水分离、传感器、光催化和医用材料在内的多个领域得到广泛应用。本文对 Janus 材料进行了系统的分类介绍，重点介绍了各种生物质基 Janus 材料（主要是纤维素基 Janus 材料、木质素基 Janus 材料和蛋白质基 Janus 材料）及其制备方法。这项工作不仅加深了对生物质基 Janus 材料的理解，也为设计基于生物质的 Janus 结构的新方法提供了帮助，以优化生物质的利用。
