First Artificial Neural Network Created Out of DNA

07-21-11

Lulu Qian, Senior Postdoctoral Scholar in Bioengineering; Erik Winfree, Professor of Computer Science, Computation and Neural Systems, and Bioengineering; and Jehoshua (Shuki) Bruck, Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering, are the first to have made an artificial neural network out of DNA, creating a circuit of interacting molecules that can recall memories based on incomplete patterns, just as a brain can.

Largest Biochemical Circuit Built Out of Small Synthetic DNA Molecules

06-02-11

Lulu Qian, Senior Postdoctoral Scholar in Bioengineering, and colleagues including Erik Winfree, Professor of Computer Science, Computation and Neural Systems, and Bioengineering, have built the most complex biochemical circuit ever created from scratch made with DNA-based devices in a test tube that are analogous to the electronic transistors on a computer chip."We're trying to borrow the ideas that have had huge success in the electronic world, such as abstract representations of computing operations, programming languages, and compilers, and apply them to the biomolecular world," says Dr. Qian.

Molecules that Behave Like Robots

05-12-10

Erik Winfree, Associate Professor of Computer Science, Computation and Neural Systems, and Bioengineering, and colleagues from Columbia University, Arizona State University, and the University of Michigan have programmed an autonomous molecular "robot" made out of DNA to start, move, turn, and stop while following a DNA track. The development could ultimately lead to molecular systems that might one day be used for medical therapeutic devices and molecular-scale reconfigurable robots—robots made of many simple units that can reposition or even rebuild themselves to accomplish different tasks.

DNA Origami Nanoscale Breadboards for Carbon Nanotube Circuits

11-10-09

Hareem T. Maune, a graduate student studying carbon nanotube physics, and Si-ping Han, a graduate student investigating the interactions between carbon nanotubes and DNA have developed DNA origami nanoscale breadboards for carbon nanotube circuits. "This collaborative research project is evidence of how we at Caltech select the top students in science and engineering and place them in an environment where their creativity and imagination can thrive," says Ares Rosakis, chair of the Division of Engineering and Applied Science at Caltech and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. The work of these students was supervised by: Erik Winfree, Associate Professor of Computer Science, Computation and Neural Systems, and Bioengineering; William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics; Paul W.K. Rothemund, Senior Research Associate, and Marc Bockrath, Associate Professor of Physics at University of California Riverside. [Caltech Press Release]
