Trapping nanoparticles with optical tweezers

By exploiting a particular property of light diffraction at the interface between a glass and a liquid, researchers have demonstrated the first optical tweezers capable of trapping nanoscale particles.

New tools 'turn on' quantum gases of ultracold molecules

JILA researchers have developed tools to "turn on" quantum gases of ultracold molecules, gaining control of long-distance molecular interactions for potential applications such as encoding data for quantum computing and simulations.

Gold- and bronze-like paints that don't contain metal

Lustrous metallic paints are used to enhance the beauty of many products, such as home decorations, cars and artwork. But most of these pigments owe their sheen to flakes of aluminum, copper, zinc or other metals, which have ...

Ultra-thin camera lenses of the future could see the light of day

In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now present a new technology for making ...

Method analyzes pollen fast, cheaply and automatically

Pollen: essential for the pollination of many plants, but the bane of allergy sufferers. Pollen warning services provide information about daily exposure and allergy risk and are an important source of information for affected ...
