Nicholas A. Kotov, FRSC (born August 29, 1965, Moscow, USSR), is the Joseph B. and Florence V. Cejka Professor of Chemical Engineering at the University of Michigan in Ann Arbor, MI.[6] He is best known for his work on the self-assembly of nanomaterials and layer-by-layer assembly (LbL)[7][8] of advanced composites. His studies have also recently expanded into the areas of implantable neuroprosthetic devices, three-dimensional cell scaffolds, and chiral nanostructures.
Biomimetic self-organization of nanoparticles is the central topic of Kotov’s research, for which he was awarded MRS Medal in 2014[1] (shared with Prof. Sharon Glotzer also of the University of Michigan). Kotov established that inorganic nanoparticles can spontaneously self-organize into chains,[9] sheets,[10] nanowires, and two-dimensional and three-dimensional particulate lattices, their geometry being determined by the anisotropy of nanoparticle interactions. The diversity and complexity of such assemblies approaches that of self-assembled structures of biomolecules.[11] A good example of the intricate self-organized assemblies possible for nanoparticles is the series of twisted ribbons prepared by Kotov’s research group that have nanoscale chirality.[12]
Supraparticles self-assembled from several hundred individual nanoparticles were reported by Kotov and coworkers in 2011,[13] and exemplify terminal self-assembled structures that can be related to other terminal assemblies such as micelles, vesicles, and virus capsids. Unlike their extended mesoscale counterparts, their size and geometry is determined by the local equilibrium state originating from the balance of repulsive and attractive interactions. The generic nature of such interactions makes possible a large variety of terminal supraparticle structures that may include different organic and inorganic components.
Kotov also investigated LbL multilayers from nanoplatelets of clay, graphene, graphene oxide, and other nanoparticles as a pathway to new materials needed for flexible electronics, energy storage, biomedical implants, and load-bearing elements. The LbL materials are made by alternating deposition of thin films of nanoparticles and polymers. Kotov found that these composites replicate the structure and mechanical properties of nacre[14] - a natural composite whose protective function was perfected by evolution. The uniform orientation and small size of nanoparticles also makes the LbL–constructed composites transparent.[14][15] The uniqueness of properties found in LbL materials[16] and boundless range of possible combinations of nanoparticles and polymers spurred widespread interest in the manufacture of nacre-like composites. For these studies Kotov received Gutenberg Award in 2008 and AICHE Stine Award in Materials Research in 2012.[citation needed]

Education and research career
Education and early career
Kotov received his MS (1987) and PhD (1990) degrees in chemistry from Moscow State University where his research concerned liquid-liquid interfaces imitating cell membranes for solar energy conversion. After graduation, he took up a postdoctoral position in the research group of Prof. Janos Fendler in the Department of Chemistry at Syracuse University, where he worked on the layer-by-layer deposition of nanoparticles[17] and graphene oxide nanosheets.[18] He also studied Langmuir-Blodgett monolayers of nanoparticles, demonstrating their organization in hexagonally packed domains and superlattices.[19]
Independent research career
Kotov took up a position as Assistant Professor of Chemistry at the Oklahoma State University in Stillwater, Oklahoma in 1996, gaining promotion to Associate Professor in 2001. In 2003 he moved to the University of Michigan where he is now the Joseph B. and Florence V. Professor of Chemical Engineering.
Professional achievements
Kotov has published nearly 250+ peer-reviewed publications. He has also filed or been granted 18 patents.
Kotov serves as an Associate Editor for the journal ACS Nano,[20] and as an advisory board member of several other nanotechnology journals. He has received more than 30 awards and recognitions from different countries, international organizations, and multinational corporations. These include the 2013 Langmuir Lecturer Award of the American Chemical Society, and the 2012 Stine Award from the American Institute of Chemical Engineers[2] for his fundamental contributions to self-assembled nanoscale colloids. In 2011 he was ranked both as one of the top 25 materials scientists[3] and top 100 chemists[4] of the decade 2000-2010 by Thomson Reuters, and the ultrastrong transparent clay/polymer composites developed in his laboratory were featured in Wired Magazine’s Top 10 Discoveries of 2007[5] for the discovery of ultrastrong nanocomposites and the development of a scaled-up method for the production of LBL materials for transparent armor. Together with his students Dr. Meghan Cuddihy and Dr. Jungwoo Lee, he used LbL coatings mimicking bone composites as a technical foundation for the commercialization of cell cultures in three-dimensional scaffolds as substrates for drug discovery.
Personal life
In 1991, Kotov married Elvira Stesikova, a PhD Chemist working on polymeric surfactants. They have two daughters, Sophia and Nicole.
