The device is universal, highly sensitive, cheaper than its analogs from popular brands – and easy to use as it is wireless. A paper describing the device has been published in Nature Communications.
ITMO Physicists Discover Way to Achieve Stimulated Raman Scattering in Isolated Silicon Nanoparticles
An optimized design of silicon nanoparticles provides а more efficient transition from spontaneous to stimulated Raman scattering. The proposed approach also allowed researchers to reduce the size and volume of particles supporting the stimulated Raman scattering regime by tens of times compared to their existing counterparts. The researchers also designed a platform in the form of a silicon nanoparticle on a sapphire surface that can be applied in sensing, detection, and thermometry, opening up new opportunities for future applications in biomedicine, targeted drug delivery, and as an alternative to electronic devices in optical chips. The results of the research were published in Nano Letters.
The method allows scientists to get an image close to a holographic one in its properties but with less energy input. In theory, the method could be applied in industrial quality control or acquiring images of concealed objects, for instance, in transillumination of envelopes.
We can often read about nanorobots in various scientific articles. They are said to be one of the most promising tools to combat serious diseases. But what are nanorobots? In this article, ITMO.NEWS joined forces with Diana Markozashvili, participant of the ITMO Fellowship and Professorship program, to answer all your questions on the topic.
