2 Microstructures (1 of 2) (IMAGE) Optica Caption This shows two microstructures made with the new material, containing the lowest concentration of RDGE. Left: Pre-carbonization. This circular table and bunny models, just slightly larger than a typical bacterium, were formed using two-photon polymerization, the preferred method of 3-D shaping. Right: The same models after they have been carbonized, or charred. Notice that they shrink significantly but maintain their shape. Credit Credit: Optical Materials Express.
