Scientists Build Tiny Robots From DNA
Scientists can now build microscopic robots with unprecedented precision, thanks to a breakthrough in nanotechnology. This groundbreaking achievement, developed at the University of Sydney, opens the door to a future where programmable nanobots tackle problems in medicine, materials science, and energy.
The team’s innovation lies in their creation process: they utilize DNA origami – the art of folding DNA molecules into complex shapes. Leading the effort were Dr. Minh Tri Luu and Dr. Shelley Wickham. This “DNA origami” technique involves pricking precise folded structures out of life’s building block, DNA itself.
“Think of it like using LEGOs, but at the molecular level,” says Dr. Wickham.
“The rules of building with DNA origami are similar to LEGO bricks
