Single-contact LEDs driven with alternating current mean brighter, sharper smart glasses. (Nanowerk News) LEDs, or light-emitting diodes, are essential components in near-eye displays like virtual ...

Researchers at Princeton University have developed a 3D printer that can print LEDs in layers -- and it could one day print contact lenses that incorporate heads-up displays. Michelle Starr Science ...

If diabetes progresses too far, it can result in a potentially blinding condition known as retinopathy. And while existing treatments are invasive and often painful, there may be new hope in the form ...

In developing techniques to fabricate homogeneous one-dimensional (1D) nanostructures, researchers have sought to control shape, aspect ratio and crystalline arrangement 8,9,10, and recent ...
