Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.
A new type of ultra-efficient, nano-thin material could advance self-powered electronics, wearable technologies and even deliver pacemakers powered by heart beats.
Researchers at the Max Planck Institute for Intelligent Systems in Germany have developed powerful nanopropellers that can be steered into the interior of cells to deliver gene therapy.
Made of electronic circuits coupled to minute particles, cell-sized robots could flow through intestines or pipelines to detect problems.
