TryNano.org is a resource for anyone interested in learning about Nanoscience and Nanotechnology. Nanoscience and Nanotechnology are technical fields that focus on matter at the nanoscale - dimensions that are roughly 1 to 100 nanometers (1nm = 10-9m).

The term Nanoscience often refers to research that discovers and characterizes new behaviors and properties of materials at the nanoscale. Nanotechnology describes how discoveries at the nanoscale are put to work, especially by controlling the behavior of matter and building useful devices. Some of these devices have demonstrated applications in medicine, electronics, robotics, and energy production.

A team of researchers, led by Boston University College of Engineering (ENG) PhD candidate Farrukh Mateen (ENG’18) and Raj Mohanty, a professor of physics at BU’s College of Arts & Sciences (CAS), are closing in on a solution. They have built a tiny micromechanical device and turned it on and off with one nanowatt of power—that’s a billionth of a watt—from three feet away. The device is a miniature sandwich of gold and aluminum nitride that vibrates, or resonates, at microwave frequencies. The tiny resonator is only 100 micrometers across—a little wider than the width of a human hair. “Wireless power is not new,” says Mateen. “Nikola Tesla demonstrated it at the 1893 World’s Fair; but we believe this is the first time it’s been used with a...
