• An Electric Shepherd for Electric Sheep: ITMO Researchers Develop Manipulator for Singular Nanoparticles

  Laboratory analysis of singular nanoparticles usually calls for specialized, expensive equipment and a lot of time; now, a new manipulator by researchers from ITMO promises to solve that problem. The add-on fits onto any microscope, doesn’t require any in-depth optics knowledge, and is easy to use. In a few minutes, it picks out a particle from the greater mass and secures it under the lens in a specific spot. The device should prove useful in identifying medical issues at early stages, developing new materials for nanoengineering, and studying the unique properties of particles in fundamental physics.

• Record-Breaking: Tiny Nanolasers for Ultracompact Chips Developed at ITMO

  Physicists at ITMO University have broken their own record for the world’s smallest nanolaser: they were able to decrease the nanoparticle’s size from 310 nanometers to 200 (which is 5,000 times smaller than a millimeter!). The new laser functions at room temperature, while the green light it radiates can be seen through a standard optical microscope. The solution can be applied in the development of fine parts for digital microdevices and wellness trackers, as well as in VR headsets: there, the nanolaser will be able to improve the quality of color rendering.

• ITMO Scientists Suggest New Synthesis Method For Nanoparticles Used in Cancer Treatment and Diagnostics

  Researchers from ITMO’s ChemBio Cluster have suggested a new way of synthesizing magnetic nanoparticles for cancer treatment and diagnostics. Thanks to machine learning at the core of the new approach, the scientists can quickly select the properties of nanoparticles for efficient MRI diagnostics and hyperthermia treatment. With the new method, the synthesis of a single nanoparticle takes just a few seconds – compared to the hours required in the conventional experimental approach. The method was described in a paper published in Small.

• ITMO Scientists Suggest Novel Nanoparticle-Based Cancer Treatment

  Cancer is the second most common death cause in the world, which in 2020 took the lives of nearly 10 million people – every sixth death, according to WHO. Globally, researchers are developing new, more efficient treatments for oncological diseases. Scientists from ITMO also contribute to these efforts: recently, they have come up with a universally applicable magnetic particle from zinc ferrite and manganese ferrite that can facilitate both cancer diagnostics and treatment. The new method increases the efficiency of radiotherapy by 40%, and during magnetic hyperthermia it can heat cancer cells in several seconds, while also securing less exposure for the healthy cells. This study was published in Journal of Materials Chemistry B.
