In Roman mythology, Janus was the god of change and transition, often portrayed with two faces gazing in opposite directions. At the University of Illinois at Urbana-Champaign, Janus particles are ...

Janus particles, which take their name from a Roman god with two faces, are microscopic 'two-faced' spheres whose halves are physically or chemically different. Now, U.S. researchers have shown that ...

A research group has developed a new COVID-19 testing system using Janus particles -- microparticles with two sides possessing distinctive molecular properties. These particles are engineered to bind ...

Microbots have made great strides in recent years as scientists and engineers work on creating cell-sized robots that can swim through the bloodstream and act as tiny medical commandos. However, such ...

(Nanowerk Spotlight) As technology advances toward flexible, adaptive devices, traditional electronics are hitting their limits due to rigidity and power demands. But what if materials themselves ...

One way or another: Janus spheres are coated with gold and platinum. (Courtesy: Vladsinger/CC BY-SA 4.0) If a micron-sized sphere is coated half in gold and half in platinum, then placed in a solution ...

Duke University engineers say they can for the first time control all the degrees of the particle’s motion, opening up broad possibilities for nanotechnology and device applications. Their unique ...

In the supplemental material the experimental setup is shown (see top image), which is designed to make the individual iron-coated polymer particles rotate. The particles are called Janus particles ...
