A combined team of engineers from Jiangsu University and Harvard University used a non-destructive, light diffraction fingerprint technique to detect viral infections in cells. Their paper is ...

"For us, it became an enabler." By carefully designing patterns smaller than the diffraction limit, the team was able to precisely control how much light reached different parts of the printing area ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...
