Scientists at Purdue University have figured out how to levitate and spin Fluorescent Nanodiamonds (FNDs) in a vacuum.

What are FNDs?

Fluorescent Nanodiamonds (FNDs) are stable, non-toxic carbon nanoparticles that emit consistent fluorescence, have a lifespan over 10 nanoseconds, and can be levitated and spun for advanced quantum research applications.

Medical Diagnostics: FNDs are used for high-resolution imaging and tracking cells over extended periods due to their non-toxic nature.
Temperature Sensing: FNDs can measure temperatures at the microscale, making them useful for scientific experiments.
Correlative Microscopy: Their fluorescent properties make them ideal for combining different types of imaging techniques.
Sensor Technologies: Due to their sensitivity to acceleration and electric fields, FNDs can be used in industry sensors and gyroscopes for rotation sensing.
Quantum Computing: FNDs doped with nitrogen can be used for quantum superposition experiments and future quantum computing applications.
