Life at the interface: Engineering bio‐nanomaterials through interfacial molecular self‐assembly

Abstract

AbstractInterfacial self‐assembly describes the directed organization of molecules and colloids at phase boundaries. Believed to be fundamental to the inception of primordial life, interfacial assembly is exploited by a myriad of eukaryotic and prokaryotic organisms to execute physiologic activities and maintain homeostasis. Inspired by these natural systems, chemists, engineers, and materials scientists have sought to harness the thermodynamic equilibria at phase boundaries to create multi‐dimensional, highly ordered, and functional nanomaterials. Recent advances in our understanding of the biophysical principles guiding molecular assembly at gas–solid, gas–liquid, solid–liquid, and liquid–liquid interphases have enhanced the rational design of functional bio‐nanomaterials, particularly in the fields of biosensing, bioimaging and biotherapy. Continued development of non‐canonical building blocks, paired with deeper mechanistic insights into interphase self‐assembly, holds promise to yield next generation interfacial bio‐nanomaterials with unique, and perhaps yet unrealized, properties.This article is categorized under: Nanotechnology Approaches to Biology > Nanoscale Systems in Biology Therapeutic Approaches and Drug Discovery > Emerging Technologies
