Diamond nanoparticles containing nitrogen-vacancy centers can now monitor cellular metabolism in real time, targeting specific organelles while tracking particle movement inside living cells.

When you're checking the freshness of a piece of fish that you plan on eating, you want results right away. That's where a new microneedle-based sensor comes in, as it delivers a yay or nay in less ...

A new fluorescent sensor is giving scientists an unprecedented view of how cells respond to DNA damage, capturing the repair process as it unfolds in real time. The tool, developed at Utrecht ...

A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system captures both detailed structures and tiny moving particles at ...

In Alzheimer’s disease, microglia act as a double-edged sword. They can either protect the brain or worsen the damage, depending on their activation state. Inflammatory activation harms healthy ...

A special sensor can accommodate various device sizes while recording accurate notes regarding substance levels such as blood, insulin, and IV fluids. A non-contact level sensor does not come into ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

Early-stage disease diagnosis relies on the highly sensitive detection of biomarkers. Optical whispering-gallery-mode (WGM) microcavity sensors have emerged as a highly promising technology for ...

Fluorescent proteins can be turned into qubits within cells and could give us a deeper understanding of biology at the nanoscale level. When you purchase through links on our site, we may earn an ...
