Real-time in-vivo thermometry on worms by nitrogen-vacancy center in nanodiamond 
(QSense OIST Mini Symposium Talk 6)​

Temperature affects various physiological functions and is one of the most important factors in homeostasis. However, these physiological functions have not yet understood from the biochemical viewpoint. While several biological samples do not have the temperature receptor, they seem to adapt the temperature. In the standard sense of theoretical physics, the "small-scale" temperature is not well defined. Recently, the room-temperature operated nano-scale thermometry is established to use the nitrogen-vacancy center in nanodiamond. This thermal probe is the bio nontoxic. This is well known as one of the best candidates on the bio-sensing applications. In our study, Caenorhabditis elegans (C. elegans) is considered. C. elegans does not have the temperature receptor but control the aging speed by temperature. As the proof-of-concept experiment on the biological application by the nanodiamond thermometry, we measured the thermogenic response of C. elegans due to the chemical stimuli. This work is basically collaborated with Masazumi Fujiwara group and Eriko Kage-Nakadai group, which are in Osaka City University.

OIST Mini-Symposium for Quantum Sensors of Magnetic and Inertial Forces

This mini-symposium is hosted by the Quantum Machines Unit in the Okinawa Institute of Science and Technology Graduate University, and will take place from Feb 1, 2021 - March 5, 2021. To get the precise schedule and zoom invitation please register below. Attendance is open to any student/faculty member from any of the institutions associated with the speakers.

Summary

Quantum systems are extremely fragile, sensitive to noise and fluctuations by their environments. This, in turn, makes them excellent sensors for a variety of forces and fields. In this mini-symposium we focus on the development of novel quantum sensors which are aimed at the precision sensing of inertial forces such as acceleration or gravity, and magnetic forces.

Such sensors - accelerometers/gravimeters or magnetometers, have a widespread application in industry such as sensing underground water movements using gravimeters, through to magnetic brain imaging using magnetoencephelography. Each week we hear from three international experts on these topics in hour-long seminars and discussions.
