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.

Researchers have synthesized a collection of nanoparticles, known as carbon dots, capable of emitting multiple wavelengths of light from a single particle. Additionally, the team discovered that the dispersion of the carbon dots, or the interparticle distance between each dot, influences the properties of the light the carbon dots emit.
