👉 The Nancy Fluid is a colloidal suspension of nanodiamonds, carbon nanotubes, and other carbon-based nanoparticles in water, discovered by researchers at the University of Rochester. These microscopic particles, typically less than 100 nanometers in diameter, exhibit unique physical and chemical properties due to their high surface area and quantum effects. When suspended in water, they form a stable fluid with exceptional optical clarity and biocompatibility, making them valuable for applications in biomedical imaging, drug delivery, and environmental monitoring. Their distinctive blue fluorescence, arising from nitrogen-vacancy centers in the diamond structure, allows for precise tracking and sensing capabilities.
