Abstract
Chemo/biosensing with optical fibres has played an important role since the 1980s mainly thanks to their invasive capabilities and unique performance that have allowed measurements inside the human body otherwise impracticable. Optical fibre-based platforms for biosensing have been also proposed, by exploiting the refractive index (RI) changes induced on chemical/biochemical recognition layers deposited on fibre surface. Long period gratings (LPGs) and lossy mode resonance (LMR) are among the two most interesting approaches, being characterized by high sensitivity to external RI changes.
