Abstract

We present a study aimed at developing fibre-optic-based biosensors for the specific detection of biological species. These sensors rely on the combined use of a Tilted short period Fibre Bragg Grating that detects changes in the refractive index of the surrounding solution and of an electrostatic self-assembly technique: self-assembled polyelectrolyte layers and immobilization of the sensor protein on the fibre surface were used for sensor fabrication. We observed changes in the sensor's spectrum induced by specific binding and we imaged fibre surface with atomic force microscopy (AFM). The results show the feasibility of the sensor for various biological or chemical applications.
