A levitated nanosphere as an ultra-sensitive sensor

Sensitive sensors must be isolated from their environment as much as possible to avoid disturbances. Scientists at ETH Zurich have now demonstrated how to remove from and add elementary charges to a nanosphere that can be ...

Controlling the stiffness of a material at the nanoscale

Using a needle far thinner than a human hair, scientists revealed how to control mechanical stiffness in a promising material. The team applied an electric field with a nano-sized needle to cause a reversible change in the ...

Direct visualization of magnetoelectric domains

A novel microscopy technique called magnetoelectric force microscopy (MeFM) was developed to detect the local cross-coupling between magnetic and electric dipoles. Combined experimental observation and theoretical modeling ...

Detecting extraterrestrial life using mechanical nanosensors

Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology. On the other hand, motion is a trait of all life, and ...
