“…With the advancement of processing technology, the fiber optic probes with a microstructure, such as bent fiber, microfiber, taper fiber, and fiber with complex construction, have also been developed for foodborne bacteria detection. The U-shaped fiber optic is a typical bent fiber that allows the propagation mode of light from the fundamental mode to high-order mode or enhances the light to interact with the surrounding, which causes the significant enhancement of the evanescent field for high refractive index sensitivity. On the basis of this principle, Mukherji’s group developed a set of analysis methods for foodborne bacteria detection using the U-shaped fiber optic, as depicted in Figure c.…”

Food safety is a concerning issue globally. Foodborne-pathogenic-bacteria-derived foodborne disease outbreaks have increased the threat to human health. The accurate and rapid detection of foodborne bacteria is of great significance for food safety. A fiber-optic-based biosensor has emerged as a powerful technique for the point-of-care testing of foodborne bacteria in food and agricultural products. This Perspective discusses the opportunities and challenges of fiber-optic-based biosensors for foodborne bacteria detection. The corresponding solution strategies to promote the application of this innovative technology in food and agricultural product detection for food safety and human health are also discussed and proposed.

“…Our previous work demonstrated that the density and orientation of the aptamers played a vital role in the aptasensor based on the Ω-shaped fiber optic. 57,58 Due to the bent area making the light propagation from the fundamental mode into the high order mode, 59 the Ω-shaped fiber optic possessed high refractive index sensitivity for the LSPR-based aptasensor when the gold nanoparticles were coated on the fiber optic surface, 60,61 as shown in Figure 3A. Compared with the traditional thiol-modified aptamer, the ployA-modified aptamer adjusted the density on the fiber optic surface through the length of the ployA.…”

Precision medicine that takes individual variability into account is a new way to minimize the individual variability for precise diagnosis and to establish the certain strategies of efficient therapy. Due to miniaturization sensing area, remoting detection, and flexible operation of light, fiber optics have been successfully used to develop in vitro, wearable, and implanted biosensors, exhibiting high potential in precision medicine from the diagnosis in vitro to therapy in vivo. When modified with the recognition element, the fiber optic‐based biosensor enables the point of care testing for the detection of disease biomarkers. Meanwhile, the fiber optics packaged in a needle/catheter also monitor the medical Internet of things for the continuous assessment of human health. Moreover, the light from the cladding or leaky mode in the fiber optics excites the strong photothermal effect for therapy. The fiber optic‐based biosensor addressed the drawbacks of plasmonic photothermal therapy that limited penetration depths and non‐selectivity therapy. When integrated with a photothermal agent, the fiber optic‐based biosensors provide in situ information for the diagnosis as well as specifically and efficiently kill the tumor cells in deep tissues. In this review, we summarized the advances of fiber optic‐based biosensors in the diagnosis in vitro and therapy in vivo. The challenges and prospection of the fiber optic‐based biosensor application in precision medicine were also explored in depth.
