Researchers from Scrona Ltd. and ETH Zurich joined forces to create the world’s smallest image certified by Guinness World Record.  All this detail is contained in only 0.0092 mm² (1.42600285e-5 in²), which is no wider than a human hair!  This equates to an astounding resolution of 25,000 DPI!

Quite fitting for its reef subject, the research team employed a type of inkjet-printable LED technology called quantum dots, which Advanced Aquarist has written about before, to paint the microscopic clownfish and anemone.  And when we say microscopic, we really mean it: only 30 µm (0.001 inches) in length!
