Researchers of the Laboratory of Nano-Bioengineering of NRNU MEPhI presented seven reports at once at the prestigious international PCNSPA Conference 2016—Photonic Colloidal Nanostructures: Synthesis, Properties, and Applications

An international on a cutting-edge line of research in nanophotonics was held in St. Petersburg from June 27 to July 1 this summer, in the romantic period of midnight sun. The PCNSPA Conference 2016 — Photonic Colloidal Nanostructures: Synthesis, Properties, and Applications was organized by the Physics of Nanostructures research and training center of the ITMO University in the framework of the Lasers and Photonics congress and was hosted in the Holiday Inn Moskovskye Vorota hotel.

Vladimir Oleinikov, PhD, DSc, presented a study on Effect of Silver Plasmonic and Semiconductor Excitonic Nanoparticles on the Bacteriorhodopsin Photocycle in Halobacterium salinarum Membranes analyzing the interactions of semiconductor quantum dots with bacteriorhodopsin, a protein contained in purple membranes of the bacterium Halobacterium salinarum.

The report A High-Performance White Light-Emitting Diode Based on Polyfluorene–Quantum Dot Two-Component Composite by Pavel Samokhvalov, PhD, and coauthors demonstrated that the shade of white light from a two-component light-emitting diode composed of modified polyfluorene and quantum dots can be controlled by varying the relative concentrations of the components of this hybrid nanocomposite without loss of efficiency.

Pavel Linkov presented a report Ultrasmall Quantum Dots for in Vivo and in Vitro Fluorescent Bioimaging describing the method of synthesis of very small defect-free CdSe nanocrystals with a high quantum yield. The method is based on an injection reaction in an organic medium, with the growth quickly stopped at the early stage of formation.

The report on Resonance Transfer of One- and Two-Photon Excitations in Quantum Dot–Bacteriorhodopsin Complexes by Viktor Krivenkov and coauthors summarized the results of studies demonstrating that the spectral region of the bacteriorhodopsin function can be extended by employing the Förster resonance energy transfer to this protein upon one- or two-photon excitation of quantum dots with a wide one-photon absorption spectra and large two-photon absorption cross-sections.

In addition to oral presentations, two reports were presented at the poster session: Simulation of the Optical Properties of Porous Silicon Photonic Crystals in the Visible Spectral Region by Dmitry Dovzhenko and Stability of the Optical Properties of the Quantum Dot–Polymethacrylate Composite under Laser Irradiation: Effect of the fabrication Method by Maria Zvaigzne.

The proceedings of the conference will be published in the Optics and Spectroscopy, the leading Russian journal in the field of advanced optical and spectroscopic research, and will be cited in the Scopus and Web of Science databases.
