Novel electron microscopy offers nanoscale, damage-free isotope tracking in amino acids

A new electron microscopy technique that detects the subtle changes in the weight of proteins at the nanoscale -- while keeping the sample intact -- could open a new pathway for deeper, more comprehensive studies of the basic building blocks of life. Scientists described the first use of an electron microscope to directly identify isotopes in amino acids at the nanoscale without damaging the samples.
