    (a) Schematic of spaser as multimodal cellular nanoprobe. (b) Comparison of emission in suspensions of uranine spaser at 528 m (green peak; pump energy fluence 70 mJ cm−2), fluorescein spaser (magenta peak), QD with maximum at 576 nm (inset, red peak) and GNRs (right) with silica shell doped with DCM. TEM images shows 22-nm spaser (left inset) and GNRs (right inset).

    A nanolaser known as the spaser can serve as a super-bright, water-soluble, biocompatible probe capable of finding metastasized cancer cells in the blood stream and then killing these cells, according to a new research study...
