In biological samples, this can be used to study embedded or attached nanoparticles and nanostructures with heavier atomic weights, such as gold or iron. Figure 1: Atomic interactions with the principal electrons (PE) and how they create the different signals. Sample preparation is an important procedure, especially for biological samples.

The complexities involved in proper sample management policies and procedures are often underestimated. Prior to initiating a study that will involve the collection of biological samples, many decisions need to be made that will affect the quality of the samples and the outcome of the study. The appropriate sample type(s) needs to be chosen.
