Introduction

Our research broadely focuses on Physico-Chemical Processes at Nanoscale and can be devided into the following categories:

Intracellular Drug Delivery and Cell Transfection: Nanotubes and nanoporous mebranes and are applied for these goals with emphasis on targeted delivery with new physical mechanisms of drug release.

2D Materials (Graphene, hBN...). Synthesis and Applications: Graphene and other 2D materials represent a new class of materials with widely expanding range of applications. We explore fundamental aspects of their growth via atmospheric pressure chemical vapor deposition (APCVD) and their applications as membranes for sensors, desalination, photovoltaic devices, composite materials and others. The work is performed in collaboration with ORNL (Dr. I. Vlassiuok)

Sensors:Various physico-chemical phenomena can often be applied to detect chemical and biological species. We have been focusing on sensors based on nanoporous membranes with simple electrical and optical means of detection. Similar approaches are used to construct smart membranes/valves that respond to physical and chemical stimuli.

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.

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 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. Intra and intermolecular charge transfer have been investigated including photovoltaic and electroluminescent devices.
