For the first time, researchers focus plasmons into nanojet

Researchers of Tomsk Polytechnic University with Russian and Danish teams have been able to experimentally confirm a plasmonic nanojet effect previously forecast in practice. Using a simple method, they focused surface plasmon ...

High-tech contact lenses correct color blindness

Researchers have incorporated ultra-thin optical devices known as metasurfaces into off-the-shelf contact lenses to correct deuteranomaly, a form of red-green color blindness. The new customizable contact lens could offer ...

Scientists expand memory effect range through spatial filtering

Speckle autocorrelation imaging is a new emergent imaging technique through scattering media, with its main advantages in simple experimental setup, single-shot fast detection and non-invasion. The prerequisite of speckle ...

Chip-based optical sensor detects cancer biomarker in urine

For the first time, researchers have used a chip-based sensor with an integrated laser to detect very low levels of a cancer protein biomarker in a urine sample. The new technology is more sensitive than other designs and ...
