Beyond polymers: New state-of-the-art 3D micro and nanofabrication technique overcomes material limitations - Phys.org

Building things so small that they are smaller than the width of a human hair was previously achieved by using a method called two-photon polymerization, also known as 2PP—today’s state-of-the-art in 3D micro- and nanofabrication. Tiny sculptures such as a mi…
