Bioengineers have successfully injected them with nanorobots made from DNA that can unfold to dispense drugs, Discovery News reports.
The nanoscale robots were made using DNA strands that fold and unfold like origami. They can function like mini-computers, carrying out simple tasks. One day similar nanorobots could be programmed to seek out diseases inside humans and treat them at the site, with medical precision.
The work is being led by Daniel Levner from Wyss Institute at Harvard University and scientists at Bar Ilan University in Israel. He and his colleagues programmed the DNA nanorobots to interact with each other and move around inside a living cockroach.
The programs were simple logical operations that directed the DNA to unfold and release a molecule, for example, when it encountered a specific protein.
