Using DNA's unique lock-and-key mode of chemical bonding, a research team at the University of Minnesota is proposing a molecular-circuit assembly technique that they believe will be compatible with silicon-based electronics. A patterned silicon substrate, complete with interconnection pads, carries DNA-coded "tiles" that serve as breadboards for nanocomponents. The components are measured in angstroms, enabling densities of 10 trillion bits per square centimeter. In the prototype system, the na

NEXT UPCOMING BROADCAST

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
