• -enhanced Raman scattering (SERS) substrates. Recently Strelau et al. reported the correlation between electrical conductivity and SERS activity [7]. For a fast, specific, and sensitive detection of molecules at low concentration, EGNP were applied for qualitative as well as quantitative SERS measurements

• time of 5 min. A number of samples were measured again after two months and we found a reproducibility of the RBS spectra within about 2 % indicating stable silver structures. SERS detection of riboflavin by using silver EGNP arrays Enzymatically generated silver nanoparticles are suitable as surface
