Microprobe
A microprobe is an instrument that applies a stable and well-focused beam of charged particles (electrons or ions) to a sample.All of these techniques involve modified optical microscopes to locate the area to be analysed, direct the probe beam and collect the analytical signal.[1][2][3] Scientists use this beam of charged particles to determine the elemental composition of solid materials (minerals, glasses, metals).Nuclear microprobes are extremely powerful tools that utilize ion beam analysis techniques as microscopies with spot sizes in the micro-/nanometre range.It is the radiation that causes changes in the sample, which in turn allows scientists and engineers to develop tiny devices such as microprocessors, accelerometers (like in most car safety systems), etc.
