In chemistry and physics, the term “quantum” refers to a specific packet of substance or energy. Energy is transferred in individual packets rather than continuously. It relates to the bare minimum of energy required for a change.
The Global Quantum Thermometer market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Nanodiamond quantum thermometer measures the temperature of worms.The nanodiamond quantum thermometers used are quite promising.
The nanodiamond used to make the probes naturally contains flaws called NV centres. These happen when a nitrogen atom and an empty lattice site take the place of two nearby carbon atoms in a diamond lattice.
Since the extra electron on nitrogen is still unpaired, it acts as an isolated spin. The direction of this spin can be “up,” “down,” or a combination of the two. By shining the diamond with laser light and observing the intensity and frequency of the fluorescence that is released, its state may be detected.
NVs in nanodiamonds are suitable as biological probes because they are non-toxic, photostable, have functionalized surfaces, and can be easily injected into living cells.
They can detect the extremely faint magnetic fields produced by neighbouring electronic or nuclear spins because they are also separated from their surroundings, which means that their quantum behaviour is not instantly impacted by ambient temperature fluctuations.
As a result, they can be utilised as extremely sensitive magnetic resonance probes that can detect small-scale changes in a material’s local spin across a few tens of nanometers
Additionally, the NV defects can detect individual target spins with nanoscale spatial resolution, in contrast to standard magnetic resonance imaging (MRI) approaches in biology, which require millions of spins to produce a detectable signal.
