A team from the NRNU MEPhI laboratories of Hybrid Photonic Nanomaterials and Nano-Bioengineering got a patent on a device for controlling and modifying molecule and substance properties by light

Rospatent, the RF Federal Intellectual Property Service, is issuing a patent on the Method for Modification of Molecule Properties in a Sample and a Device for Its Implementation, an invention by I.R. Nabiev, D.S. Dovzhenko, K.E. Mochalov, A.V. Mezin, P.M. Sokolov, and Yu.P. Rakovich.

The device developed in the Laboratory of Hybrid Photonic Nanomaterials (LPNM) and Laboratory of Nano-Bioengineering (LNBE) makes it possible to change the electrical conductivity, chemical reactivity, deuterium exchange rate, and many other physical and chemical parameters of a sample placed into it, as well as modify various processes, such as energy transfer efficiency and lasing. The device employs the effect of light–matter coupling when the electromagnetic radiation mode comes into resonance with the electron or vibrational transition of the sample's molecules. A microcavity consisting of a plane and convex mirrors and ensuring plane–parallelism in at least one point on the convex mirror surface is the core of the device. The resonance is attained by fine (nanometer-precise) adjustment of the distance between the mirrors, which is how the microcavity is tuned to a given electron or vibrational level of the sample in it, this level being then split by the radiation.

This invention is just one result of a series of research and developments in the field of light–matter interactions in the strong and weak coupling regimes carried out jointly by LPNM and LNBE. The approach underlying it has already been highly appreciated by the scientific community: the authors' publication on this subject became an editor's pick in the top-rated international journal Review of Scientific Instruments, as reported in the NRNU MEPhI news >>, and the flagship paper "Light–matter interaction in the strong coupling regime: configurations, conditions, applications" by Dmitry Dovzhenko, Semyon Rybchuk, Yuriy Rakovich, and Igor Nabiev was recently published by another top-rated journal, Nanoscale, which has also been reported at the MEPhI website >>.

It's a special pleasure that this is the first patent got by LPNM, a laboratory fairly recently established in NRNU MEPhI under the direction of Prof. Yuriy Rakovich in the framework of the Russian federal Mega-Grant program.
