Abstract:
Surface plasmon resonance (SPR) is a popular technique that allows for sensitive, specific, label-free and real-time assessment of biomolecular interactions. SPR is a nondestructive, modular and flexible tool for various applications in biomedical sciences ranging from cell sorting, cell surface characterization and drug discovery. In this review, we will discuss more specifically how SPR is used to monitor the dynamics of various types of cellular binding events and morphological adherence changes in response to external stimuli.
