First Full-Color Micro Images Produced with a 100,000-dpi Resolution

“Similar to a child’s ‘coloring-by-numbers’ image, the sizes and positions of these nanostructures defined the ‘numbers’. But instead of sequentially coloring each area with a different ink, an ultrathin and uniform metal film was deposited across the entire image causing the ‘encoded’ colors to appear all at once, almost like magic!” continued Dr. Yang.
