Biomolecules such as proteins, nucleic acids, and polysaccharides serve as the building blocks of all organisms, but it’s the interaction among these molecules that plays an even more critical role in biology. Therefore, understanding these interactions is central to biological sciences and essential for biomedical research, environmental monitoring, therapeutic developments, and more. Two different approaches are used in the study of the biomolecular interactions: the labelled approach in which the interacting biomolecules should carry a monitoring label (such as a fluorescent tag), and the label-free approach in which no labelling is required…
