Atoms are many orders of magnitude smaller than cells. Atoms range from about 0.1 to 0.5 nanometers wide. Cells range from about 0.1 to 100 micrometers wide. 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 ... ... nm, and which should be useful, if probes smaller than antibodies are employed. As the antibodies place the fluorophores at a substantial distance from the ... ... nm to 140 nm. In addition to measuring the spherical size of the virus ...
