Abstract:
1. A method of producing a titanium based Surface Enhance Raman Scattering (SERS) sensor, comprising: providing a titanium substrate having a surface and producing an array of sensor locations in a predefined portion of the surface by irradiating the predefined portion of the surface in the presence of air with laser pulses having an intensity, a wavelength, a pulse duration, an effective irradiation time and a pulse repetition rate selected to produce, at each sensor location, a micro-pattern feature in the surface of the substrate and a self-supported web structure that generally surround and envelop the micro-pattern feature, said self-supported web structured being made of nanofibers each comprised of a plurality of titanium based nanoparticles aligned into said self-supported web structure, wherein said array of sensor locations exhibit SERS activity.
