　　Biomass materials possess inherent advantages in the development of biomimetic materials and offer an essential pathway for achieving high-value utilization of biomass. However, the intrinsically complex structure of biomass nanomaterials impedes precise structural manipulation, material performance optimization, and the further development of high-value applications. To address these challenges, we highlight recent advancements in biomass technology through colloidal control, particularly by utilizing interfacial confinement environments to manipulate biomass materials and enable dynamic, biomimetic functionalization precisely. This presentation will cover two interfacial regulation strategies for biomass materials. The first involves the precise control of electrostatic assembly of nanocellulose and nanochitin at the aqueous two-phase interface, enabling the on-demand construction of advanced functions such as selective mass transfer, controllable sub-surface migration, and liquid-in-liquid 3D printing. Collectively, we establish a microcapsule reactor system characterized by self-migration, self-initiation, and self-termination. In the second strategy, living microorganisms are regulated at the water-oil interface to synthesize cellulose, leveraging the continuous mass transfer properties of the two-phase system to enable multiphase biomanufacturing. This approach facilitates the convenient and efficient construction of multilayer hydrogels, porous materials, and core-shell microcapsule structures. Such dynamic biomimetic strategies for biomass provide new theoretical directions and technical pathways for developing green new material systems that combine high conversion efficiency with high added value.
