Complexity, Disorder, and Functionality of Nanoscale Materials

Abstract: Nature hosts a wealth of materials showcasing intricate structures intertwining order, disorder, and hierarchy, delivering resilient multifunctionality surpassing perfect crystals or simplistic disordered materials. The engineering of such materials through nanoparticle assembly represents a burgeoning field, poised with potential to yield sustainable material systems rivaling or exceeding biological functionalities. This review delineates the fundamental concept of complexity in the context of nanoscale materials. It examines methodologies for characterizing complexity and functionality, explores pragmatic approaches to create complex nanomaterials, and offers a perspective on their potential applications, guiding the trajectory of future research endeavors.
