the SERS trace-detection core (paper, flexible, silicon, dewetting, alloy substrates all live here)
VAD-SERS turns a single alumina column into both a reversed-phase chromatography medium and a native SERS sensor — separating and fingerprinting food colorants, flagging dye adulteration, and deconvoluting real candy colours, all read in-column on the RAMaker (532 nm).
Inserting a 5.5 nm fluorine-doped tin oxide interlayer between ZnO:Cu nanoneedles and silver nanoparticles lifts a SERS substrate to a 5.95×10⁸ enhancement factor and a 1 femtomolar rhodamine-6G detection limit — every result measured on the MRID (532 nm).
A guide to the SERS substrates ProTrusTech has helped validate — paper, flexible, silicon, gold and dual-function platforms, grouped by the problem each solves.
Gold nanoparticles grown with grape-skin extract, paired with graphene oxide on paper, give a 1.9×10⁹ SERS enhancement and 10⁻¹¹ M dye detection in food.
An ionic-liquid electropolymerization route patterns hydrophobic wells on ITO and flexible film — droplet arrays for electrochemistry and SERS on the MRI.
Two studies, one idea: semiconductor nanowire arrays that photocatalytically destroy a dye and, decorated with silver, detect it by SERS down to 10⁻⁹ M.
A grating-patterned, silver-nanowire-decorated PDMS film stays SERS-active through bending, twisting, stretching, acid, cold, and even vapor detection.
An automatic writing machine draws silver nanowire ink onto paper — and reaches a femtomolar detection limit that beats every other AgNW method tested.
One silver-nanowire platform, two signals, three years — how Protrustech and Nanovie co-developed NanoSE from pesticide sensing to a COVID-19 assay.
Silver-on-silicon SERS substrates made in 3 minutes at room temperature, no vacuum gear — and exactly what a pyramid texture buys you in sensitivity.
