“…For some time now, metal deposition on highly rough surfaces (notably, those which exhibit a certain nano‐structurization) has been used to fabricate highly SERS‐active substrates with metal nanoparticles on the surface . Typically, such ‘composite’ SERS substrates are formed by the deposition of silver nanoparticles on porous ‘inert’ oxides (Al 2 O 3 and TiO 2 ) . In this contribution, we report the strong impact of the type of substrate on the SERS properties of deposited metal particles.…”

Silver nanoparticles deposited on various 'inert' porous materials (mainly Al 2 O 3 and TiO 2 ) are often used as substrates for surface-enhanced Raman scattering (SERS) measurements. In this study, we used the sputter deposition technique to cover tubular arrays of Al 2 O 3 and TiO 2 with Ag nanoparticles. Raman spectra of pyridine (as a probe molecule) and of two selected dyes (5-(4-dimethylaminobenzylidene)rhodanine and 5-(4-(dimethylamino)benzylidene)-3-(3-methoxypropyl)rhodanine) adsorbed on fabricated Ag/TiO 2 -n/Ti and Ag/Al 2 O 3 -n/Al substrates were measured. We found that the SERS spectra of pyridine adsorbed on Ag nanoparticles deposited on an Al 2 O 3 -n/Al substrate are distinctly different from those measured for an Ag/TiO 2 -n/Ti composite. Similar effects were observed for dyes adsorbed on the surface of both composites. The spectral differences between two kinds of composites (Ag/TiO 2 -n/Ti and Ag/Al 2 O 3 -n/Al) are discussed in terms of (1) the modified electronic structure of the Ag nanoparticles due to their interaction with different substrate materials and (2) the different atomic topology of the metal particles thus deposited on the surfaces of the substrates. Composite samples were also studied with the aid of scanning electron microscopy (SEM) and Auger electron spectroscopy (AES) to reveal their characteristic morphological and chemical features.

“…7 An ideal SERS substrate must have sufficient Raman signal enhancement to be able to detect the analyte while, at the same time, having a homogenous surface able to produce reproducible Raman spectra. 8 Various methodologies for fabrication of SERS substrates using e-beam lithography, 9 anodized aluminum oxide templates 10 and nanoimprinting 11 have been reported. Recently, we have developed a new and simple maskless lithography method to produce flexible, free standing goldcapped nanopillar (Au NP) structures suitable for molecular detection at ultra-low concentrations.…”

The orientation of pterin-6-carboxylic acid on gold nanopillars was investigated by surface enhanced Raman spectroscopy and density functional theory methods. The experimentally vibrations from pterin-6-COOH free and attached to the Au surface display vibration features indicating chemical interaction of the pterin with the metal surface. The spectral feature evidenced that the pterin would adsorb on gold surface with a "lying down" configuration through the high intensity vibration of NH scissoring and rocking OH modes. The orientation study of pterins on gold nanopillars presented herein is believed to lead to new applications in biosensing field for detecting pterins of physiological importance.

“…1,2 In the past 30 years, much attention has been paid to fabricating SERS substrates with considerable enhancement through a number of methods, including colloidal chemistry, 3,4 galvanic displacement reaction, [5][6][7][8][9] template assisted method, [10][11][12][13] and evaporation (or magnetron sputtering). [14][15][16] Compared with 1D and 2D structures, 3D structures have great advantages in use as SERS substrates. 3D structures, especially at the nanoscale, can offer increased surface area, promoting the formation of hot spots and the capture of target analytes.…”
