A microstructured fiber for streptavidin detection

The properties of the microstructured optical fibers (MOFs) make them a growing photonics sensing platform with a wide range of applications in medicine, biological, and chemical detection. Particularly in the detection of bio/chemical analytes using the MOFs, the main advantage is the integration of the optical transducer and fluidic part in the unique MOF platform. In this work, we report a Kagome-based lattice MOF for the detection of streptavidin molecules. Interaction between the light coupled into the fiber in form of the LP-like modes and analytes attached to the fiber’s internal surface will result in the analyte detection. This study shows that the Kagome-based MOFs can be used for protein molecule detection.
