Abstract
The quality of optical biosensor data must be improved in order to characterize the mechanism and rate constants associated with molecular interactions. Many of the artifacts associated with binding data can be minimized or eliminated by designing the experiment properly, collecting data under optimum conditions and processing the data with reference surfaces. It is possible to globally fit high‐quality biosensor data with simple bimolecular reaction models, which validates the technology as a biophysical tool for interaction analysis.
