Faster testing of new pharmaceuticals

To improve medical treatment, researchers test new drug ingredients on biological cells. By combining two microscopy techniques, the time required for testing can be reduced by 50 to 80 percent. And far fewer measurements ...

Optical techniques examine toxic agents in cells

EPFL researchers have developed a method for accurately determining the toxicity of nanomaterials. By using optical techniques, they are able to measure the concentration of the oxidizing substances produced by a damaged ...

Express tool for graphene quality control

The National Physical Laboratory (NPL) has collaborated with Chalmers University of Technology and Linköping University in Sweden to help develop a fast and inexpensive tool for quality control of graphene grown on silicon ...

New nanoscale imaging method finds application in plasmonics

Researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland have shown how to make nanoscale measurements of critical properties of plasmonic nanomaterials—the specially engineered ...

NIST shows how to make a compact frequency comb in minutes

Laser frequency combs-high-precision tools for measuring different colors of light in an ever-growing range of applications such as advanced atomic clocks, medical diagnostics and astronomy-are not only getting smaller but ...
