Silicon Origami Folds From Flat To 3-D With A Drop Of Water
Scientists in the Netherlands have created flat shapes that open and close with a droplet of water into tiny cubes, pyramids and other three-dimensional structures.
With more research, the self-assembling, silicon-based shapes could lead to microscopic packages of drugs that release their therapeutic cargo directly where it is needed. The 3-D structures, about the size of a sand grain, could also open and close at specific locations, allowing for noninvasive microbiopsies from deep within the body.
“Possible shapes are in principle limitless as long as they can first be made on a flat surface,” said University of Twente graduate student Antoine Legrain.
