SURFACE PLASMON RESONANCE (SPR) SPECTROSCOPY

Surface Plasmon Resonance (SPR) has emerged as a powerful detection technique for the study of molecular binding processes due to its high sensitivity and label-free capability. SPR as a optical-based real-time detection method delivers superior results across diverse categories of research. Applications include life science, drug discovery, electrochemical analysis, food quality and safety, environmental science, and chemical sensor development. From life science to environmental safety, determining which molecules interact, how they interact, and why they interact can ultimately lead to more effective drugs, higher performance materials, cleaner air/water quality, and much more.

Several technologies exist that may be utilized for such molecular binding studies, i.e. ELISA, QCM, and ITC. However, few encompass as many advantages as surface plasmon resonance. SPR enables (1) high sensitivity, (2) label-free detection, (3) real-time monitoring, (4) low volume sample consumption, (5) quantitative evaluation, and (6) determination of kinetic rate constants. Furthermore, SPR is easy to perform and can be a cost-effective solution.

RotaLab provides SPR instruments that use a unique detection method to achieve both high sensitivity and fast detection speeds. Our innovative design and BI-DirectFlow™ technology allows us to combine precise sample delivery at small volume with a noise and drift cancellation technique to meet the diverse application needs of our users. In addition, our novel modular design enables users to perform various applications such as electrochemistry and gas phase SPR with ease.
