Revealing the fluctuations of flexible DNA in 3-D

First-of-their-kind images by Berkeley Lab-led research team could aid in use of DNA to build nanoscale devices.

Educating and inspiring students through nanotechnology

New educational videos and a nanotech-enabled superhero contest are among new activities to educate and inspire students to prepare for high-tech jobs of the future.

An up-close view of bacterial motors

Over millennia, bacteria have evolved a variety of specialized mechanisms to move themselves through their particular environments. In two recent studies researchers used a state-of-the-art imaging technique to capture, for the first time, three-dimensional views of this tiny complicated machinery in bacteria.

Nanoparticle-based cancer therapies shown to work in humans

Scientists have shown that nanoparticles can function to target tumors while avoiding adjacent healthy tissue in human cancer patients.

How to make metal alloys that stand up to hydrogen

High-tech metal alloys are widely used in important materials such as the cladding that protects the fuel inside a nuclear reactor. But even the best alloys degrade over time. Now, researchers has found a way of greatly reducing the damaging effects these metals suffer from exposure to hydrogen.

A biomimetic 'bridge' to precision medicine

Researchers have developed a technique that uses antibody-coated nanoparticles as imaging probes to watch cell-to-cell interactions under microfluid conditions.

We don't talk much about nanotechnology risks anymore, but that doesn't mean they're gone

The worries that even nanotechnology proponents had in the early 2000s about possible health and environmental risks - and their impact on investor and consumer confidence - seem to have evaporated. So what?s changed?
