WebbNanoparticles are nearly-spherical particles of diameter between 1 and 100 nanometers. They consist of thousands of atoms, but are still much too small to be directly visible with a light microscope (here I like to draw a line and put various sizes on it: 0.1 nm = atoms, 1–100 nm = nanoparticles, 200 nm = visible with light microscope). WebbNanotechnology is the study of incredibly small particles that are measured in nanometers. A nanometer is one billionth of a meter. Nanoparticles are small particles having at least one dimension that is smaller than 100 nanometers. Part 1: Measuring in nanometers 1. Examine the metric ruler. This ruler is 1 meter long.
