Light incident on metallic nanoparticles can initiate the collective motion of electrons, causing a strong amplification of the local electromagnetic field. Such plasmonic resonances have significant roles in biosensing with ...
Holograms are a ubiquitous part of our lives. They are in our wallets—protecting credit cards, cash and driver's licenses from fraud—in grocery store scanners and biomedical devices.

(PhysOrg.com) -- A new "transfer-printing" method of making light-sensitive semiconductors could make solar cells, night-vision cameras, and a range of other devices much more efficient, and could transform the solar industry.
This week, researchers reported on the implications of a warp drive containment breach in case you're interested in theoretical space-borne disasters. Scientists in the U.K. report the cardiovascular benefits of COVID-19 ...
Shooting a movie in the lab requires special equipment. Especially when the actors are molecules—invisible to the naked eye—reacting with each other.
