In the first part, the attention will be focused on some fundamentals of fiber sensors and the most common parameters used to describe the performance of any fiber sensing and biosensing platform by underlining the difference between volume or bulk sensing and surface or add-layer sensing (or biosensing). In the second part, some remarkable examples of resonance-based fiber optics devices from the state-of-the-art literature will be presented. In particular, the combination of such devices with nanotechnology, such as deposition of nanocoatings, nanoparticles or nanostructures in general, will be deeply discussed with final “food for thoughts” examples.
