Twisted meta-molecules as they really are

Physicists have devised a clever way to truly test the chirality of a material, eliminating the risk of false positives from other techniques.

Nanotweezer lab-on-a-chip holds promise of early cancer diagnosis

Researchers used plasmonics to develop a new kind of nanotweezers that can rapidly trap and detect molecules, viruses and DNA - a device transformative for medicine that also has color printing applications.

Asymmetric plasmonic antennas deliver femtosecond pulses for fast optoelectronics

Researchers have succeeded for the first time in generating ultrashort electric pulses on a chip using metal antennas only a few nanometers in size, then running the signals a few millimeters above the surface and reading them in again a controlled manner.

Efficient, eco-friendly production of fine chemicals with single-atom catalyst

Chemical engineers have developed a new catalyst for forming a bond between two carbon atoms in a cost-effective and eco-friendly way.

Engineer creates new design for ultra-thin capacitive sensors

The thin and flexible sensor is ideal for sensing sounds because it can move with the airflow made by even the softest noises and addresses issues with accelerometers, microphones and many other similar sensors.

Team's e-whiskers may be a touchstone for future of electronic skin

Researchers used shape-memory polymers to create artificial, electronic versions called e-whiskers, which mimic the properties of the real thing.

Nanomaterials could mean more algae outbreaks for wetlands, waterways

High tech metal particles may inadvertently take a toll on aquatic life.
