Cells are squishy and soft. Tiny nanometer-sized particles such as quantum sensors cannot move freely inside them due to viscous drag, which makes sensing challenging. Researchers at the Indian ...

Quantum mechanics states that electrons have two stable spins—up and down. With the advent of nanoscale fabrication methods, device companies are harnessing this knowledge to create devices. The ...

BENGALURU: In a step towards probing the inner workings of living cells with precision, researchers from IISc have developed a technique to actively steer quantum sensors through the dense, viscous ...

Diamond quantum nanoprobes detect immune cell inflammation by sensing electric charge shifts, opening a new path for real-time single-cell monitoring in immunology and cancer research. (Nanowerk ...

Crystals doped with rare-earth (RE) ions exhibit very narrow linewidths of the optical transitions. The narrow-line spectra of triply ionized RE elements cover the entire visible and infrared range.

A man walking around a room wearing a helmet that records his brain function would have seemed like science fiction five years ago. Now researchers have designed a lightweight helmet with tiny ...

Quantum tech is going green. A new take on highly sensitive magnetic field sensors ditches the power-hungry lasers that previous devices have relied on to make their measurements and replaces them ...

With a few exceptions primarily at the quantum-physics level, sensors of real-world parameters are inherently analog. The formal designations of the parameters being sensed are fairly clear, such as ...
