Photonic fibers borrow from butterfly wings to enable invisible, indelible sorting labels

Less than 15% of the 92 million tons of clothing and other textiles discarded annually are recycled—in part because they are so difficult to sort. Woven-in labels made with inexpensive photonic fibers, developed by a University ...

Label-free imaging of red blood cells and oxygenation with color TSFG microscopy

Cells and tissues rely on the circulation of red blood cells (RBCs) for oxygen supply. Two-photon (2P) microscopy is a reference technique for measuring RBC microcirculation and blood oxygenation using exogenous phosphorescent ...

Interaction-free, single-pixel quantum imaging with undetected photons

To capture an image of an object, a photographer typically requires a source of light interacting and scattering away from that object of interest, and a method to detect the light being scattered away from that object, as ...
