Research interests

Breakthroughs in synthetic chemistry and characterization techniques of 1-3 nanometer atomic precise clusters covered by a monolayer of organic molecules have made the manipulation of gold nanoparticles with atomic and molecular precision possible over the last decade. Ability to sense the environment, understand and control molecules and matter in the nanoscale, can be introduced to the nanostructures by chemically modifying nanostructure surfaces with suitable molecules. In materials science there is a need for well-defined self assembled structures and new functionalities. This requires mastering the size and structural uniformities of the building blocks, as well as the complex interplay of competing interactions.
