As a Renaissance polymath skilled in painting, science, and engineering (to name just a few of his interests), we think Leonardo da Vinci would have been impressed by a recent project carried out by researchers at the California Institute of Technology. They have taken his iconic Mona Lisa painting, probably the world’s most famous piece of art, and reproduced it at nanoscale using strands of DNA. Sized just 700 nanometers in width, it’s the world’s tiniest ever re-creation of the “Mona Lisa” — which originally measures at 2.53 by 1.74 feet.
“We developed a series of rules for assembling simpler DNA nanostructures into more complex superstructures,” Philip Petersen, a graduate student in the department of biology and biological engineering, told Digital Trends. “Further, [we] demonstrated the applicability of those rules by creating unprecedentedly large DNA ‘canvases’ capable of having arbitrary patterns drawn upon them.”
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
