Abstract
In this work, porous TiO2 nanostructures consisting of vertically aligned nanotube arrays were grown by anodic oxidation and decorated with silver nanoparticles employing sputtering deposition. The hybrid metal-semiconductors were used as SERS active substrates and fully integrated into microfluidic devices. Remarkable R6G limit of detection down to 10-14 M and good homogeneity of the SERS signal was found for the optimized substrates. The biosensing performance of Ag-TiO2 nanotubes based optofluidic device was tested exploiting an optimized protocol for oligonucleotides detection
