George Chumanov Ph.D.

Dr. Chumanov's current research consists of three parts: the preparation and modification of different nanoparticles, including one-, two- and three-dimensional regular structures; the investigation of their properties using different spectrochemical techniques together with optical, electron, atomic force and scanning tunneling microscopy; and the development of new materials and devices for environmental and biomedical diagnostic applications.

His concentration is on metal, metal/semiconductor and metal/dielectric hybrid nanoparticles, which exhibit unique optical properties due to the excitation of so-called plasmon resonances (plasmons). Plasmons can be effectively tuned by changing the size, shape, composition and local environment of nanoparticles, making them the ideal building blocks for the next generation of optical materials, electronic and photonic devices.

Education

Chumanov received his B.S. at Moscow Engineering Physics Institute and his Ph.D. (1988) from Moscow State University, working with Professor Edward Manykin in the field of optics and spectroscopy of biomolecules.
