A sprocket of research engineers (yes, apparently that's the collective noun for a group of engineers) at the Catalan Institute of Technology (CIT) has succeeded in breaking the record for sensitivity of mass measurement. By measuring the resonant frequency of a short length of single carbon nanotube, masses as small as a single nucleon (proton or neutron), having a mass of about 1.7 yoctogram (1 yg = 10^-24 grams) were measured, thereby exhibiting a level of sensitivity several orders of magnitude better than previous devices. This new technology enables the detection and identification of individual atoms and molecules and tracing the fate of individual atoms in a chemical reaction...
