Interfacial assembly in biological systems is crucial for structural integrity and adaptive functionality, yet the soft and flexible nature of biointerfaces, especially in aqueous environments, poses challenges for material-centric biointerface engineering. To address this, we propose polyphenol-based interfacial engineering. The catechol- and galloyl-rich motifs of polyphenols enable diverse molecular interactions favorable in water, making them versatile building blocks for the bottom-up assembly of nanoscale coatings and interfacial architectures. To demonstrate this, we introduce two recent studies: (1) the PAINT technique for site-specific fabrication of melanin-like pigments on soft matter via controlled interfacial polymerization, and (2) a liquid-core fiber system integrating liquid-like diffusion with solid-like mechanical support. Together, these examples highlight polyphenol-based assemblies as a promising platform for functional and bioinspired soft matter interfaces.
