Morphology analysis includes qualitative and quantitative analysis of a sample, which is crucial for many research studies. With the development of micro/nanofabrication techniques, micro- and nanostructures provides a unique way of controlling biomolecule-surface interactions. It has been shown that surface feature and roughness strongly affect protein adsorption on designated biomaterials surfaces. 

Compositional analysis always refers to quantitative chemical/elemental analysis of a given sample. In materials science research, compositional analysis is a valuable tool because it enables researchers to identify unknown material, and understand the structure–property relationships for each component and their synergistic behaviors to characterize significant changes in the material structure and elemental distribution. For example, it has been found that the char yield, char combustion time and char combustion rate of woody biomass pellets are mostly depended on their composition. Pellets made of bark had up to a 50% longer char combustion time compared to that of stem wood pellets, due to differences in char yield. Quantitative chemical analysis methods are also used occasionally for evaluation of foreign material contaminants in special cases for failure analysis or investigation of product manufacturing or handling problems.
