nanosphere
Microscopic spherical particle
A nanosphere is an extremely small spherical particle, typically measuring between 1 and 100 nanometers in diameter—roughly a thousand times smaller than a red blood cell.
Nanospheres appear in materials science, medicine, and nanotechnology, where they serve as drug delivery vehicles, contrast agents for imaging, or building blocks for advanced materials: The researchers loaded the nanospheres with chemotherapy drugs to target tumor cells directly.
