Using a process known as DNA origami, researchers at Caltech in Pasadena, CA were able to create their own rendition of van Gogh’s The Starry Night, only theirs is about the width of a dime in size and glows a deep red. Employing folded strands of DNA, the team could precisely place and tune fluorescent molecules within a microscopic 256 x 256 pixel grid (that’s 65,536 total pixels for those of us who don’t math very well) of what they call PCCs (photonic crystal cavities).
“It’s like using DNA origami to screw molecular light bulbs into microscopic lamps”
The project is a proof-of-concept aimed at the development of chips and circuitry on a nano-scale and has practical applications throughout all fields of technology, including quantum computing.
