New Discovery Makes Cheap, Compact Lasers Possible
Researchers from ITMO have demonstrated a novel technique for generation of laser radiation that utilizes perovskite metasurfaces. The solution will pave the way for next-gen lasers that are less than 100 nm thick and require significantly less energy. The invention can be incorporated into compact photonic chips for light control or used as an intense light source in medicine (e.g., for tissue or blood diagnostics), materials processing, astronomy, and other fields. The results of this study were published in the journal Advanced Functional Materials.

ITMO Researchers Develop Simple Technology for Fabrication of Microfluidic Elements on Glass
Scientists from ITMO’s Institute of Laser Technologies have developed a new technology that creates structured microfluidic elements, including channels, reservoirs, and spirals, on a silica surface. Importantly, the novel fabrication method requires only a laser and a single operator, while the resulting structures can be used in microfluidic chips for biomedical research and diagnostics of cancer, diabetes, and cardiac impairments. The results of the study are described in a recent article in Optical and Quantum Electronics.

ITMO Researchers Developing New Cancer Treatment Using Gold Nanoparticles and Infrared Lasers
In recent years, oncological diseases have become one of the most wide-spread causes of death in developed countries – and despite the abundant new diagnostics and treatment methods, fighting cancer is still a challenge. Nearly all known treatments have significant side effects, while some of them are even helpless against more persistent cancer cells. One solution to this problem is photothermal therapy, on its own or in combination with other treatments. Researchers from ITMO University have suggested a new method to treat melanoma more effectively and safely using gold nanoparticles. Read on to learn more about the new method.

Scientists Use Lasers and Gold Particles to Turn Titanium Oxide Into Nanocomposite for Photocatalysts
Oxides of different metals often serve as photocatalysts in various systems such as air purification, reactions of water decomposition and even in the production of self-cleaning surfaces for glass and mirrors. The physical-chemical properties of such materials can be improved by adding nanoparticles, which turn an ordinary oxide into a nanomaterial with new capabilities. To successfully perform this, however, it is necessary to understand the processes going on as a nanocomposite is being formed, and to be able to control them. ITMO University researchers together with their colleagues from France and the USA have demonstrated how a femtosecond laser can be used to tune the structure and nanocomposite properties for titanium dioxide films filled with gold nanoparticles. The paper was published in ACS The Journal of Physical Chemistry C.
