Get diamonds, take temperature: Quantum thermometer using nanodiamonds senses a ‘fever’ in tiny worms C. elegans – Phys.org

A team from Osaka City University, in collaboration with other international partners, has demonstrated a reliable, precise, microscope-based thermometer using quantum technology that measures the temperature fo microscopic animals. The technology detects temperature-dependent properties of quantum spins in fluorescent nanodiamonds.
The research is published in Science Advances.
The optical microscope is one of the most basic tools for analysis in biology, using visible light to to observe mic…
