Scientists Print A Monet With A Nanoprinter

“Regular printing—the kind your home office inkjet is capable of—uses dots of pigments to create the spectrum of colors you see on a page. The type of printing the Singapore team is investigating instead uses microscopic pillars topped with aluminum nanodisks that resonate at visible light frequencies. The process is able to produce more than 300 colors by focusing beams of electrons onto variously-sized pillars.”
