Research Projects in his group can be devided into the following categories: Sensors: Various physico-chemical phenomena can often be applied to detect chemical and biological species. We are trying to build a 'universal' sensor based on nanoporous membranes. Intracellular Drug Delivery and Cell Transfection: Nanoporous membranes and nanotubes are applied for these goals. Electron transfer: Electron transfer processes play a fundamental role in chemistry, physics and biology. Such processes can be initiated by light or, instead, result in a formation of electronically excited species able to emit optical photons. We investigate the photoinduced electron transfer reactions in solutions and at interfaces. Transient displacement current technique, fluorescence spectroscopy and kinetics as well as scanning probe microscopy and magnetic resonance spectroscopy are primary tools in these studies. Specific research projects include study effects of symmetry on electron transfer process, influence of electric and magnetic fields on ion-radical reactions, surface self-assembly and surface modification, and others. Scanning probe microscopy: Many chemical and biochemical phenomena can be now addressed almost on a single molecule level. Scanning probe microscopy in a form of STM, AFM and their various modifications have become powerfull tools in such in such investigations. We applying them to study mechanical and electrical properties of single molecules and their agrregates on surfaces. Dr. Smirnov also teaches the following courses:
