Chemical-Sensing Displays and Other Surprising Uses of Glass
This article mostly looks at new uses for Gorilla Glass, including using it as a chemical sensor.
“The ability to turn your phone into a biological and chemical sensor is one of the earliest-stage projects in the lab. Researchers at Corning and Polytechnique Montreal discovered that they could make very high quality waveguides, which confine and direct light, in Gorilla Glass. The researchers were able to make these waveguides very near to the surface, which is essential for sensors. Doing so in ordinary glass would break it. Making the waveguide involves focusing a beam of intense laser light near the surface of the glass, then tracing it along the glass, which locally changes its optical properties.”
