Label-free biomolecular interaction analysis is aimed at understanding the connections among biomolecules and the outcomes arising from these specific associations. This form of analysis plays a pivotal role for medical research and in the pharmaceutical industry. The interactions between biomolecules are of great importance to understand many biological processes. Although certain proteins operate independently, the majority of proteins are only active when they form complexes with other molecules. Biomolecule interactions are fundamental to all cellular processes such as signal transduction and metabolic pathways.
