Abstract
Nature encloses a myriad of precise hierarchical organizations of nanoarchitectures/microarchitectures which provide unlimited sources for the design of a wide range of attractive materials. Mimicking complex structures of nature toward the design of hierarchical materials with outstanding properties for sensing and energy storage applications is becoming a revolutionary concept in recent years. The present contribution is aimed to provide an overview of the design of advanced functional bionanomaterials for a wide range of applications, mostly related to energy conversion and storage.
