Abstract
The label-free detection of DNA strands based on Double Tilted Fiber Bragg Grating (DTFBG) has been demonstrated. The external fiber surface has been modified with peptide nucleic acid (PNA). The changes of the interference fringes visibility of the grating, due to the PNA-DNA binding, proved the occurred fiber hybridization. The re-use of the fiber for multiple measurements and the selectivity of the sensor have been also investigated
