This year, ITMO University hosted the third winter school “It’s Your Call!” for participants of the “I am a Professional” student competition. Sberbank served as the general partner of the school that annually brings together students from all over Russia. The school consists of workshops, lectures and tours of major companies and research institutions. Last week, the participants went to Laser Systems, a high-tech company based in Strelna. There, they discovered how lasers can help make flights safer and detect the level of someone’s alcohol intoxication and saw a 3D printer working with metal powders.
The concept is based on the interaction of resonant semiconductor iron oxide Fe2O3 nanoparticles with light. They can get heated locally by a laser and convert the absorbed light into heat. If you modify the shell of the polymer containers (capsules) that are widely used as a carriers for the delivery of bioactive compounds in cells and irradiate them with a laser, the heat will deform the capsules and the loaded compounds will be released at the desired location and time. The research was published in Laser and Photonics Reviews.
