Nano-Platform Ready: NYU, University of Melbourne Scientists Use DNA Origami to Create 2D Structures

Scientists at New York University and the University of Melbourne have developed a method using DNA origami to turn one-dimensional nano materials into two dimensions. Their breakthrough offers the potential to enhance fiber optics and electronic devices by reducing their size and increasing their speed.

A new type of supercapacitor that can hold a charge when it takes a lickin’ has been developed by engineers at Vanderbilt University. It is the first “multi-functional” energy storage device that can operate while subject to realistic static and dynamic loads – advancing the day when everything from cell phones to electric vehicles will no longer need separate batteries.
