Exciting developments at MIT: Engineers have found a way to assemble arrays of quantum rods in devices using scaffolds made of folded DNA, enhancing depth in virtual reality scenes! 👇
“When they’re all pointing in the same direction on a 2D surface, then they all have the same properties of how they interact with light and control its polarization.”
“The quantum rods sit on the origami in the same direction, so now you have patterned all these quantum rods through self-assembly on 2D surfaces, and you can do that over the micron scale needed for different applications like microLEDs,” Bathe further explained. As part of their research, the scientists had to conceive of a method to attach DNA strands to the quantum rods. They engineered a process that involves emulsifying DNA into a mixture with the quantum rods, then rapidly dehydrating the mixture. This system takes only mere minutes and results in the DNA molecules forming a dense layer on the surface of the rods.

Engineers Design a Robot That Can Stick To, Crawl Along, and Sail Around Rubble Pile AsteroidsAsteroids come in many shapes and sizes. Most are spherical, though many have a feature that can make them difficult to land on – they are essentially just collections of rocks loosely bound together by gravity. In space exploration jargon, they are known as “rubble piles.” Many of the asteroids humanity has visited are considered … Continue reading 'Engineers Design a Robot That Can Stick To, Crawl Along, and Sail Around Rubble Pile Asteroids'
