Fiber Optic Surface Modifications for Improved Plasmonic Biosensing

Fiber optic – surface plasmon resonance (FO-SPR) instruments are powerful optical tools with great applicability in biosensing mainly because they allow real-time quantification of biochemical interactions. Besides they bring further advantages such as simplicity portability and cost-effectiveness. These benefits came however with the price of a lower stability and sensitivity when compared to the bulky prism-based SPR platforms motivating and fueling the general research framework captured in this book i.e. to look for novel schemes of improving the innovative FO-SPR biosensing technology. In particular this work connects technology-related elements with biochemical assays development aiming the design of FO-SPR devices with improved performance and extended functionality needed in the context of an increasing demand for low-cost user-friendly and sensitive biosensors for various applications.
