Jean-Yves Rauch and colleagues at FEMTO-ST Institute constructed this 15-μm-tall house out of thin silica membranes. The team used a dual-beam scanning electron microscope and focused ion beam to erect the teeny domicile. They could cut, etch, fold, and weld the membranes within an accuracy of 10 nm. This image was taken using the scanning electron microscope. The researchers say their system can be used to build three-dimensional microsystems and will provide a new way to imbue carbon nanotubes, biosensors, and other systems with light-trapping functions.
