Scientists invent ‘bubble-pen’ to inscribe nanoparticles

Existing lithography methods, which are used to etch or pattern materials on a substrate, are not capable of fixing nanoparticles to a specific location with precise and arbitrary control. (Reuters) Scientists have developed a new ‘bubble-pen’ that uses microbubbles to inscribe nanoparticles on a surface, an invention that could help in the manufacturing of many devices like tiny machines, optical computers and solar panels.
