Unique semiconductor with huge implications invented
In this schematic representation, a hydrated polymeric nanoparticle is exposed to near-infrared light. The NIR heats pockets of water inside the nanoparticle, causing the polymer soften and allowing encapsulated molecules to diffuse into the surrounding environment.

The image shows a “multilayered waveguide taper array.” The different wavelengths, or colors, are absorbed by the waveguide tapers (thimble-shaped structures) that together form an array.
Rainbow-catching waveguide could revolutionize energy technologies
