A team of researchers from the Institute of Materials Science at Kaunas University of Technology (KTU), Lithuania together with colleagues from Japan and Latvia came up with a method that forces over 300 million metal nanoparticles to self-assemble into regular structures, which enhance their interaction with light by orders of magnitude. This work might be beneficial in developing ultra-small lasers that can contribute to the diagnostics of many illnesses, including oncological ones.
