(Nanowerk Spotlight) Infrared spectroscopy allows scientists to study molecules by analyzing their unique vibrational signatures, which act as chemical fingerprints. However, conventional infrared ...

In an advance in microsensor technology, researchers have unveiled an ultra-sensitive gas detection method using surface acoustic wave (SAW) sensors enhanced by the physics of exceptional points (EPs) ...

As they report in the journal Biosensors and Bioelectronics (Surface-acoustic-wave-driven graphene plasmonic sensor for fingerprinting ultrathin biolayers down to the monolayer limit), the SAW would ...

This breakthrough opens the door to integrating acoustic wave technologies directly into standard chip architectures.

A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an ...

Infectious diseases afflict millions of people every year. These hard-hitting viruses can rapidly sweep through populations and, in some cases, whole continents in a matter of weeks. Identifying and ...

The passive PT-symmetric model for SAW sensor. a The schematic diagram of the coupled resonators model and the real part of the eigenfrequency surfaces in the parameter space (ω1=ω2=ω0=0,γ0=0). The ...
