In this Keynote talk, we present label-free optical fiber biosensors having a quasi-random spectral pattern. These structure enable a very easy and salable fabrication of devices, while detecting molecules with high specificity and low detection limits. We propose multiple designs, and introduce applications to biosensing in medical contexts, for cancer biomarker detection, probing media such as saliva and tears, as well as detection of large particles such as viruses and cancer cells.
