Researchers at Columbia University have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance. In a recent study published in Angewandte Chemie International ...
Researchers have found an easy way to produce carbon nanoparticles that are small enough to evade the body's immune system, reflect light in the near-infrared range for easy detection, and carry payloads of pharmaceutical ...
Chemists from Europe's Graphene Flagship review the potential for graphene-organic composite materials in electronics. The researchers show how organic semiconductors can be used to better process graphene, and to tune its ...
A vibrational spectroscopic imaging technology that can take images of living cells could represent an advanced medical diagnostic tool for the early detection of cancer and other diseases.
Criminals with a penchant for dyeing their hair could soon pay for their vanity. Scientists have found a way to analyze hair samples at crime scenes to rapidly determine whether it was colored and what brand of dye was used. ...
