Magnets, all the way down!

In many ways, magnets are still mysterious. They get their (often powerful) effects from the microscopic interactions of individual electrons, and from the interplay between their collective behavior at different scales. ...

Nanobowls offer a way to magnetically deliver drugs in the body

Imagine a device that could transport drugs to any diseased site in the body with the help of a small magnet. Researchers at the University of California San Diego have taken a step toward that goal by developing nano-sized ...

New remote-controlled microrobots for medical operations

For the past few years, scientists around the world have been studying ways to use miniature robots to better treat a variety of diseases. The robots are designed to enter the human body, where they can deliver drugs at specificlocations ...

Sandcastles inspire new nanoparticle binding technique

If you want to form very flexible chains of nanoparticles in liquid in order to build tiny robots with flexible joints or make magnetically self-healing gels, you need to revert to childhood and think about sandcastles.

Nanoparticles to kill cancer cells with heat

Heat may be the key to killing certain types of cancer, and new research from a team including National Institute of Standards and Technology (NIST) scientists has yielded unexpected results that should help optimize the ...
