Fabrication and characterization of silver deposited micro fabricated quartz arrays for surface enhanced Raman spectroscopy (SERS)
In this work microfabricated silver coated two-dimensional quartz gratings are developed for the use as plasmonic arrays for surface enhanced Raman spectroscopy (SERS). The SERS technique provides enormous signal intensity and fingerprint specificity and is a powerful tool in chemical and biological applications. However, the acceptance and the employment of the SERS technique for (bio)analytical devices depends on the availability of suitable substrates with homogenous field enhancement properties. Here, the fabrication and optimization process of the SERS array with an enhancement factor between 105 and 106 is introduced.
