👉 An "at fluid" refers to a type of fluid commonly used in certain scientific and industrial applications, particularly in the context of atomic force microscopy (AFM) and other nanoscale measurements. At fluid is a liquid that has been specially formulated to have precise and consistent properties, such as viscosity, surface tension, and chemical composition, which are crucial for accurate and reliable measurements. These fluids are often tailored to minimize artifacts and ensure the stability of the sample during scanning or manipulation, making them indispensable in high-resolution imaging and surface analysis at the nanoscale.
