Surface-Enhanced Raman Scattering from Silver-Plated Porous Silicon
Abstract
Silver micro- and nanocrystallites are prepared on porous Si substrates by immersion plating, and their activity toward SERS (surface-enhanced Raman scattering) is assessed. Scanning electron microscopy reveals a rough silver film containing randomly spaced dendritic structures. SERS spectra of Rhodamine 6G (R6G) and adenine are obtained using an 18-mW, 488-nm laser. The SERS signal from these analytes is dramatically improved by pretreatment of the silver-plated porous Si samples (Ag−PS) with a 1 mM mineral acid solution. Detection of R6G and adenine from 1 nM solutions is demonstrated, corresponding to (at most) 9 × 10 5 molecules in the experimental configuration used in the current study. Ag−PS samples that have been stored in air for 10 days still display high sensitivity. The presence of chloride either in the analyte solution or in the pretreatment solution is found to dramatically reduce the limit of detection for R6G.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
