Systems allowing label-free molecular-level detection are expected to have enormous impact on biochemical sciences. Research focuses on materials and technologies based on exploiting the coupling of light ...

Nanomaterial self-assembly imaged in real time

A team of researchers from UC San Diego, Florida State University and Pacific Northwest National Laboratories has for the first time visualized the growth of 'nanoscale' chemical complexes in real time, demonstrating that ...

Researchers learn to control graphene with lasers

New numerical simulations by Berkeley Lab Alvarez Fellow Alexander Kemper and his colleagues at Stanford University reveal how the quantum properties of graphene can be manipulated at ultrafast timescales ...

Measuring the mass of molecules on the nano-scale

Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements ...

QLEDs meet wearable devices

The scientific team, from the Institute for Basic Science (IBS) and Seoul National University, has developed an ultra-thin wearable quantum dot light emitting diodes (QLEDs).

Bio-standards for high-resolution microscopy

Modern microscopes use in-built magnification scales for routine calibration. However, recent advances in high-resolution technologies and a clear shift towards more automated systems challenge the accuracy ...
