Nanoscale Lasers Kill Cancer Cells from the Inside

Jun-16-19 Nanoscale lasers called spasers could fight cancer by targeting and destroying the cancer cells one by one.

Created by a team from the University of Arkansas, the spasers (Surface Plasmon Amplification by Stimulated Emission of Radiation) measure only 22 nanometers wide, which allows them to target cancer cells without affecting the body’s natural cells. The tiny spacer would kill the cancer cells by generating an extremely bright light within the cells, and then transforming that light into heat, nanobubbles and sound waves.

The team believes that the spasers could eventually be delivered to tumor sites, where the would destroy the cancer cells one-by-one without damaging the surrounding tissue.
