Scientists build thinnest-possible LEDs to be stronger, more energy efficient

University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics. The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

Microneedle patch could replace standard tuberculosis skin test

A team led by University of Washington engineers has created a patch with tiny, biodegradable needles that can penetrate the skin and precisely deliver a tuberculosis test. The researchers published their results online Aug. 26 in the journal Advanced Healthcare Materials.

Silicon-based nanoparticles could make LEDs cheaper, greener to produce

Researchers at the University of Washington have created a material they say would make LEDs cheaper and greener to manufacture, driving down costs to consumers.
