Surface plasmon resonance analysis of dynamic biological interactions with biomaterials

Surface plasmon resonance (SPR) is an optical technique that is widely gaining recognition as a valuable tool to investigate biological interactions. SPR offers real time in situ analysis of dynamic surface events and, thus, is capable of defining rates of adsorption and desorption for a range of surface interactions. In this review we highlight the diversity of SPR analysis. Examples of a wide range of applications of SPR are presented, concentrating on work relevant to the analysis of biomaterials. Particular emphasis is given to the use of SPR as a complimentary tool, showing the broad range of techniques that are routinely used alongside SPR analysis.
