• New Technology for Drug- and Enzyme-Delivery Fluorescent Microparticles Suggested at ITMO

  Researchers from ITMO, St. Petersburg Academic University and the Institute for Analytical Instrumentation of the RAS have developed a technology for producing fluorescent microparticles with nanocrystals based on silver, indium, and sulfur. Compared to traditional organic pigments, such particles are less toxic and more resistant to laser radiation. These can be used in biomedicine to visualize blood vessels from the inside, determine the blood flow, and as carriers of treatments and enzymes. The results of the study are published in ACS Omega.

• ITMO Graduate and UbiQD’s Senior Director of Physics Nikolay Makarov: A Scientist’s Interests Must Always Be In Flux

  Nikolay Makarov was a student at ITMO University in the late ‘90s to early ‘00s. In that time, his scientific interests shifted from programming to experimental physics. His work caught the attention of an American university, where he eventually got his PhD. Since then, Nikolay has lived in the US, having worked at various universities, research institutes, and even at the Los Alamos National Lab. Today, he works at UbiQD, a private manufacturer of quantum dots. ITMO.NEWS got in touch with Nikolay and learned about his story, why young scientists don’t stick around for long at American universities, and the prospects of US-Russian scientific collaboration.

• ITMO University Professor Joins Nanomaterials as Special Issue's Guest Editor

  Today, physicists, chemists, and materials scientists around the globe seem to have immersed themselves in the world of nanostructures, which promises us materials for unique lasers, remarkably efficient solar cells, quantum computers, and high-resolution monitors. But how efficiently can modern physics explain all the processes taking place in the nanoworld? Do theoretical and experimental physicists have enough reliable and simple tools to solve fundamental problems concerning nanomaterials? These questions are the subject of the special issue of the international peer-reviewed journal Nanomaterials". Its guest editor is Anatoly Fedorov, the head of the International Research and Education Center for Physics of Nanostructures and a professor at ITMO University.

• Holographic Quantum Dot Laser in Progress

  How can we make a laser that will work effectively on low pump energy, be quite small and will allow dynamically changing the output radiation spectrum?  Vladimir Borisov, a  PhD  student at ITMO’s Department of Photonics and Optical Information Technologies, has won a grant of the Russian Foundation for Basic Research for creating just such a laser. One of the advantages of the new device is that the resonator is placed in the active laser medium, which simplifies the design while changing the resonator itself; it is created by  holographic  grating and uses quantum dots as photon sources.
