Allows for more easily building tiny machines, biomedical sensors, optical computers, solar panels, and other devices — no complex clean room required; portable version planned.

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have created “bubble-pen lithography” — a device and technique to quickly, gently, and precisely use microbubbles to “write” using gold, silicon and other nanoparticles between 1 and 100 nanometers in size as “ink” on a surface.
The new technology is aimed at allowing researchers to more easily build tiny machines, biomedical sensors, optical computers, solar panels, and other devices.
