Many developments improve the analysis of biological systems. Examples of rapidly expanding fields in this area are genomics , DNA sequencing and related research in genetic fingerprinting and DNA microarray ; proteomics , the analysis of protein concentrations and modifications, especially in response to various stressors, at various developmental stages, or in various parts of the body, metabolomics , which deals with metabolites; transcriptomics , including mRNA and associated fields; lipidomics - lipids and its associated fields; peptidomics - peptides and its associated fields; and metalomics , dealing with metal concentrations and especially with their binding to proteins and other molecules.

Chemical properties can be contrasted with physical properties , which can be discerned without changing the substance's structure. However, for many properties within the scope of physical chemistry , and other disciplines at the boundary between chemistry and physics , the distinction may be a matter of researcher's perspective . Material properties , both physical and chemical, can be viewed as supervenient ; ., secondary to the underlying reality. Several layers of superveniency [ clarification needed ] are possible.
