“…Therefore, SPR sensors can be used for the detection and sensing applications of unknown analytes, such as biomolecular components, lipids, proteins, and carbohydrates [ 24 ]. In another study, Wang et al used an Au film-modified fiber U-shaped structure cascaded multi-channel fiber SPR sensor to detect glucose and sucrose [ 15 ]. The sensor is useful for the simultaneous measurement of numerous parameters and may be immediately put into a tiny space for measurement.…”

“…As a result, fiber-based biosensors have gained popularity and provide a novel approach for the wide range detection of biological analytes [ 5 , 6 , 7 , 8 ]. Many geometrically modified and microstructured fibers, including side-polished fibers [ 9 , 10 ], D-shaped fibers [ 11 , 12 , 13 , 14 ], U-shaped fibers [ 15 ], tapered fibers [ 16 , 17 , 18 , 19 ], microsphere structured fibers [ 20 , 21 ], photonic crystal fibers (PCF) [ 22 , 23 , 24 , 25 ], and grating fibers [ 26 , 27 , 28 , 29 , 30 ], are employed to draw the guiding mode out of the cladding to interact with the surrounding environment. In order to further increase the sensitivity in the detection of bio-analytes at low concentrations, long period gratings (LPG) [ 31 , 32 ] and tilted fiber gratings (TFG) [ 28 , 33 , 34 ] are frequently used in biosensors.…”
