Nature-Inspired Engineering Separation Materials and Devices.

Abstract

Separation is a fundamental process in natural living systems. Their separation capabilities have inspired the design of various separation materials and devices. Despite some progress having been made, a comprehensive overview is still lacking. In this Perspective, we first review the development of separation technologies. We then summarize some typical living systems exhibiting superior separation capabilities from compositions and microstructures to separation mechanisms. Next, we highlight key advancements in nature-inspired separation materials and integrated devices. Finally, we propose future research directions and opportunities, emphasizing the importance of physical and chemical design and internal and external stimulus regulation. These nature-inspired materials and devices show great potential in biomedicine, environmental remediation, energy conversion, food safety, and analysis testing.
