This paper describes a bio-sensor based on a functionalized microstructured optical fiber with a Bragg grating, for specific DNA target sequences detection. The inner surface of the fiber has been functionalized using PNA probes that allows hybridization of the target DNA. To achieve sensing enhancement, functionalized gold nanoparticles were used. Experimental measurements show the high selectivity and sensitivity of the bio-sensor.

Abstract

This paper describes a bio-sensor based on a functionalized microstructured optical fiber with a Bragg grating, for specific DNA target sequences detection. The inner surface of the fiber has been functionalized using PNA probes that allows hybridization of the target DNA. To achieve sensing enhancement, functionalized gold nanoparticles were used. Experimental measurements show the high selectivity and sensitivity of the bio-sensor.
