Laser method promising for detecting trace chemicals in air

Researchers have developed a new laser-based method that can detect electric charges and chemicals of interest with unprecedented sensitivity. The new approach could one day offer a way to scan large areas for radioactive ...

New record: 3-D-printed optical-electronic integration

Optoelectronic integration offers a promising strategy to simultaneously obtain the merits of electrons and photons when they serve as information carriers, including high-density communication and high-speed information ...

Lasers aim to replace scalpels in cutting-edge biopsy technique

To a patient, the analysis of a tissue biopsy sample to check for something like cancer may seem like a relatively simple process, even if it does mean giving up a small piece of flesh to be tested. The sample heads off to ...

Tiny droplets open the doors to in-flight imaging of proteins

For the first time, researchers have demonstrated the creation of a beam of nanodroplets capable of delivering a variety of biological samples, from cell organelles to single proteins, virtually free from any contaminations, ...
