Scientists in Singapore researching a new colour printing technique have created a mini Monet - a painting measuring just three times the width of a strand of human hair.
Researchers looking into the field of plasmonics - how light behaves - used aluminium as a nano-metal to reproduce French impressionist painter Claude Monet's Impression, Sunrise, measuring 300 by 250 microns.
Usually, plasmonic colour printing is done using gold or silver but using aluminium - the third-most abundant element on Earth - is way cheaper, about one-thousandth of the usual cost.
The painting was printed at the Agency for Science, Technology and Research's (A*Star) Institute of Materials Research and Engineering. The project was a collaboration between the Singapore University of Technology and Design (SUTD), the National University of Singapore and A*Star, and was led by SUTD's Assistant Professor Joel Yang. Their research has practical applications in digital printing, data storage and security tagging.
