Summary: High-temperature superconductors have the potential to revolutionize energy generation, but the challenge lies in quickly detecting hot spots. This study uses closely spaced fibre Bragg gratings to establish a long sensor for distributed hot-spot monitoring, and the results show that the sensor can rapidly detect small hot spots under high-temperature conditions.

Summary: We developed an affordable and portable homogeneous fiber optic chemiluminescent immunosensor (hoFOCI) for rapid and on-site detection of chloramphenicol (CAP) in food stuffs. The hoFOCI integrated the immunoassay and detection platform, allowing biorecognition and signal conversion without washing steps. The hoFOCI showed a good linear response to CAP with a detection limit of 2.95 pg/mL, and demonstrated high accuracy and reproducibility in assaying CAP in real honey samples.
