“…Forming a solid-liquid composite lubricant, these materials improved the lubricity and stability of joint cavities in murine models. Cao et al created pillar-like nanopatterns of polyvinyl alcohol (PVA) polymers at solid-liquid interfaces by using a honey-comb patterned porous template (Figure 7) (Cao, Yabu, & Huh, 2020). The structured film was subsequently coated with CdS crystals to create a multilayered structure that mimicked the morphology of the moth eye.…”

Interfacial 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

The wettability and adhesion of biological surfaces often depend on their periodically arranged hybrid micro–nano array structures. Various fabrication processes are designed to mimic biomimetic micro–nano array surfaces. This review summarizes the types of micro–nano array structures and analyzes fabrication methods based on top‐down and bottom‐up construction, including templating, etching, self‐assembly, and electrospinning/electrospraying. This review focuses on the shape reconfiguration of surface micro–nano array structures under physical stimuli, as well as the changes in material surface properties during the reconfiguration process. In addition, the applications of biomimetic micro–nano array composite surfaces in the fields of droplet transport, adhesion properties, sensors, and soft robotics are also discussed, and the current challenges and prospects in this field are identified.

“…As the porous films are composed of the polymer framework and pores, their use can be applicable to frameworks and pores [ 121 ]. Compared with the vigorous progress of the framework, the applications of pores is less reported, acting as secondary templates [ 105 , 114 , 122 ], selective antibacterial surfaces [ 5 , 113 , 123 ], catalysis [ 70 , 71 ], selective cell culturing [ 5 , 123 ], drug capture and release [ 95 , 115 ], or in protein recognition [ 87 , 89 ], as shown in Figure 21 . Thus, how to develop the new functions of the cavities becomes very meaningful, which will bring new vitality to the field of porous films.…”

Recent developments in the field of the breath figure (BF) method have led to renewed interest from researchers in the pore-selective functionalization of honeycomb-patterned (HCP) films. The pore-selective functionalization of the HCP film gives unique properties to the film which can be used for specific applications such as protein recognition, catalysis, selective cell culturing, and drug delivery. There are several comprehensive reviews available for the pore-selective functionalization by the self-assembly process. However, considerable progress in preparation technologies and incorporation of new materials inside the pore surface for exact applications have emerged, thus warranting a review. In this review, we have focused on the pore-selective functionalization of the HCP films by the modified BF method, in which the self-assembly process is accompanied by an interfacial reaction. We review the importance of pore-selective functionalization, its applications, present limitations, and future perspectives.
