• ITMO Physicists Develop Multifunctional Material for Thermal Melanoma Therapy

  Researchers at ITMO have suggested a quick and simple method to synthesize gold plasmonic nanodiamonds – these hybrid materials can find their application in photothermal therapy of melanoma. The new material can perform two functions: heat up a tumor and measure its temperature. In vitro experiments demonstrated that once plasmonic nanodiamonds were introduced into a tumor and heated, the tumor’s growth slowed down by 65.22%. The results of the study were described in Nanophotonics.

• ITMO Scientists Develop Ultracompact Optical Switch

  The new device includes a structure of single-atom semiconductors and an ultracompact nanoresonator. The switching is conducted with light, via changes in the exciton states in each of the two semiconductor layers. Thanks to its ultracompact size (10 nanometers long and 1.5 nanometers thick), the device can be placed on a chip for use as a logic element in computers for optical information processing. The results of this study, conducted in collaboration with Pohang University of Science and Technology (POSTECH, South Korea), are described in an article published in ACS Nano.

• Invisible Material: Researchers Model Metasurfaces in Hybrid Anapole Modes for the First Time

  Global trends are leaning towards miniaturization, minimalism, and portability – and that's the case for research, too. These days, metasurfaces are gaining popularity as platforms for super-thin devices equal, or sometimes superior to, their "normal-sized" counterparts. This is achieved thanks to “invisible” particles in anapole modes. Recently, these particles have revolutionized nanophotonics, but researchers from ITMO, Moscow, and Riga went even further and developed hybrid anapole modes. Their new model is more efficient than its predecessors and opens new applications for metasurfaces in optics.
