Double Tilted Fiber Bragg Grating for label-free DNA detection

Double Tilted Fiber Bragg Grating for label-free DNA detection

We present a new approach for developing a label-free biosensor for detection of DNA. The biosensor based on a biofunctionalized Double Tilt Fiber Bragg Grating transduces the presence of DNA into a change of visibility of fringes of its interference spectrum. Real-time spectral measurement results...

description We present a new approach for developing a label-free biosensor for detection of DNA. The biosensor based on a biofunctionalized Double Tilt Fiber Bragg Grating transduces the presence of DNA into a change of visibility of fringes of its interference spectrum. Real-time spectral measurement results are reported, showing that a 10nM DNA solution induces a 10% modulation of the corresponding fringes visibility.
