Professor Kotov is committed to engaging in the “most creative, forward looking, and unorthodox scientific and engineering discoveries.” His research activities, publication record, and extensive practical realizations of his discoveries confirm that his efforts have a substantial impact both for fundamental science and technology.
Realization of the technological potential of nanomaterials requires their purposeful organization traversing multiple scales. After the synthesis of nanoparticles and other nanocomponents, finding such methods is regarded as one of the greatest challenges of nanotechnology. Professor Nicholas Kotov is nominated for the Welch Award for his contributions to the development of cornerstone techniques for preparation of organized nanostructured materials with controlled assembly patterns extending from nano- to macroscale. His primary contribution is the discovery of self-organization of nanoparticles driven by anisotropic force fields around them into discrete and extended superstructures. He also carried out pioneering studies of layer-by-layer assembled nanoparticle materials beyond solely polymeric system enabling preparation of diverse family nanoparticle-polymer multilayers. His works laid the foundation of the theory and practice of these widespread methods of nanoscale organization and elaborated the contribution of different forces for both techniques. Using a variety of nanoparticles from a variety of semiconductors, metals, and metal oxides, Professor Kotov demonstrated the possibility of spontaneous assembly of nanoparticles into superstructures of increasing complexity: from simple one-dimensional chains to sophisticated three-dimensional constructs such as semiconductor and metal helices. His works also trace the pathway from simple nanoparticle monolayers to purposefully assembled stratified nanoparticles multilayers with finely controlled optical, electrical, and mechanical properties. The generic nature of forces resulting in self-organization phenomena translated in simplicity and universality of these methods which led to their wide adoption in many research groups and companies around the world. It also enabled several breakthrough technologies from sensing to transparent armor and neural implants. Later studies have highlighted profound parallels between self-organization of artificial nanoparticles and analogous processes in biology providing fundamental guidelines for new discoveries related to biomedical applications of nanoparticles for treatment of cancer, Alzheimer’s syndrome, and arthritis.
