“…Since no excitation light source is required, the experiment setup is simplified and no extra instrument is needed for removing scattered excitation light. The selectivity and sensitivity are improved over conventional techniques such as absorbance, reflectance and fluorescence [74]. A fiber optic biosensor was developed to monitor the enhancement of chemiluminescence due to the addition of enhancers [75].…”

(ABSTRACT)Fiber-optic Fabry-Perot interferometric (FFPI) sensors have been widely used due to their high sensitivity, ease of fabrication, miniature size, and capability for multiplexing. However, direct measurement of self-assembled thin films, receptor immobilization process or biological reaction is limited in the FFPI technique due to the difficulty of forming Fabry-Perot cavities by the thin film itself. Novel methods are needed to provide an accurate and reliable measurement for monitoring the thin-film growth in the nanometer range and under various conditions. In this work, two types of fiber-optic multicavity Fabry-Perot interferometric (MFPI) sensors with built-in temperature compensation were designed and fabricated for thin-film measurement, with applications in chemical and biological sensing. Both the tubing-based MFPI sensor and microgap MFPI sensor provide simple, yet high performance solutions for thin-film sensing. The temperature dependence of the sensing cavity is compensated by extracting the temperature information from a second multiplexed cavity. This provides the opportunity to examine the thin-film characteristics under different environment temperatures.To demonstrate the potential of this structure for practical applications, immunosensors were fabricated and tested using these structures. Self-assembled polyelectrolytes served as a precursor film for immobilization of antibodies to ensure they retain their biological activity. This not only provides a convenient method for protein immobilization but also presents the possibility of increasing the binding capacity

“…16,[18][19][20][21][22][23][24] In this research, it was found that the weak ECL signal from the electrochemical oxidization of Ru(bpy)3 2+ was greatly enhanced by PRO. Based on this observation, CE coupled with ECL detection was used for the determination of the pharmacokinetics of PRO in human urine.…”
