A faster, more efficient imaging system for nanoparticles

Researchers have developed a new system for imaging nanoparticles. It consists of a high-precision, short-wave infrared imaging technique capable of capturing the photoluminescence lifetimes of rare-earth doped nanoparticles ...

Nanoparticles glow through thick layer of tissue

(Phys.org)—An international research team has created unique photoluminescent nanoparticles that shine clearly through more than 3 centimeters of biological tissue—a depth that makes them a promising tool for deep-tissue ...

Training light to cool the material it strikes

(Phys.org)—Light might one day be used to cool the materials through which it passes, instead of heating them, thanks to a breakthrough by engineers at Lehigh and Johns Hopkins Universities.
