Molecular interactions are the driving force behind life as we know it. These interactions include Enzymes interacting with other proteins or molecules, proteins binding to DNA or antibodies binding to viruses and many more. To better understand these interactions, we need to be able to measure them as precisely as possible.
Being able to measure the affinity, specificity and the kinetics of these interactions is of utmost importance in various areas of research, including drug development. Using the specific binding of certain biomolecules to each other can also be used in biosensing applications, where one of these molecules can be used to detect the presence and concentration of the other.
Information about molecular interactions, such as affinity, specificity and kinetics, can be obtained using SPR (Surface Plasmon Resonance).
