Nanosensors embedded in living plants detect arsenic

Researchers have developed a living plant-based sensor that can in real-time detect and monitor levels of arsenic, a highly toxic heavy metal, in the soil.

Faraday fabrics with MXene coatings?

MXene-coated fabric could contain electronic interference in wearable devices.

Artificial visual system of record-low energy consumption for the next generation of AI

Researchers have built an ultralow-power consumption artificial visual system to mimic the human brain, which successfully performed data-intensive cognitive tasks. Their experiment results could provide a promising device system for the next generation of artificial intelligence (AI) applications.

Trapping nanoparticles with optical tweezers

By exploiting a particular property of light diffraction at the interface between a glass and a liquid, researchers have demonstrated optical tweezers capable of trapping nanoparticles.

A nature-inspired glue for writing liquid metal ink onto any surface

For the first time, researchers havedeveloped a biomimetic sticky liquid metal ink that can be written on any surface with a ballpoint pen. The preparation of the ink takes inspiration from the sticky substances secreted by various marine organisms to survive under strong tidal forces by attaching themselves onto solid surfaces. The concept demonstrated in this study will provide a new avenue for next-generation electronics, sensors and functional devices.
