Physicists Unveil Tiny New Cancer-Busting Nanolasers

Physicists at Northwestern University have created perhaps the smallest tunable laser beam ever, according to ​a new report in Nature Communications. The work, which exploits the peculiar tendencies of particles known as surface plasmons, paves the way toward new and better ways of detecting cancer biomarkers in very low concentrations, e.g. rooting out cancer while it's still easily treatable—or treatable at all.
