Figure 1. (a) Schematic diagram of the optical trapping-enhanced SERS optofluidic detection system; (b) effect of the single-beam optical trap module switch state on AgNPs aggregation; (c1) and (c2) ...

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...
