Summary:

- Researchers at the University of Sydney have developed a new technology called "Velcro DNA" that can be used to assemble nanorobots and other nanoscale structures.
- The Velcro DNA technology uses DNA strands that can selectively bind to each other, similar to the way Velcro fasteners work, allowing for the precise and reversible assembly of complex nanostructures.
- This technology has potential applications in areas such as drug delivery, biosensing, and nanomedicine, as it enables the creation of customizable and programmable nanodevices.
