title: New applications of the nuclear microprobe for biological samples.
abstract: The continuing development of the Nuclear Microprobe (NMP) has opened up new fields of applications in biology and medicine. Quantitative multielemental analysis in small sections of samples can be performed routinely. The use of techniques such as scanning transmission ion microscopy makes imaging as well as mass normalization possible at submicron resolution. Recent medical applications include studies on thin cryosections prepared from autopsies and biopsies, as well as single cells grown directly on the backing foil used in the NMP analyses. The purpose of the single cell analysis is often pharmacological, e.g., testing of new drugs, their uptake and distribution. New applications, for instance, in food chemistry, ecology and evolutionary genetics, are also taking advantage of the high analytical sensitivity of the NMP in combination with its imaging capability.
