• Researchers Present New Synthesis Method for Optically Active Carbon Nanodots

  One of the most remarkable carbon-based nanomaterials are luminescent carbon dots, the physical and chemical properties of which are easy to control. Thanks to their low toxicity, these particles are said to possess great potential in the fields of biology and medicine. Carbon dots are made from organic substances; if their precursor contains a chiral center, the resulting nanoparticles will be chiral, too. These particles have various application prospects, including in medical diagnostics. Researchers from ITMO University and St. Petersburg State University, in collaboration with their international colleagues, have developed a new way to synthesize such nanoparticles with stable optical properties.

• Researchers Demonstrate a Platform for Future Optical Transistors

  Leading research groups in the field of nanophotonics are working toward developing optical transistors –  key components for future optical computers. These devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem for microelectronics engineers. A group of researchers from ITMO University, together with colleagues, have come up with a new solution to this problem by creating a planar system where photons couple to other particles, which enables them to interact with each other. The principle demonstrated in their experiment can provide a platform for developing future optical transistors. The results of their work are published in Light: Science & Applications.
