Micro-origami: Micrometer-scale 'Voxels' Folded Up For Drug Delivery

Wednesday, April 30, 2008 - 13:55 in Physics & Chemistry

Researchers have demonstrated a way to manufacture minuscule closed containers that might be used to deliver precise micro- or even nano-quantities of drugs. First the scientists create flat patterns, origami, of exactly the fold up shapes familiar to kindergarten children making paper pyramids, cubes or other solids, except that these are as small as 30 micrometers on a side. (1 inch = 25,400 micrometers)
