Abstract

Gold Nanopearls In article number 2207404, Chihchen Chen, Tzung-Hai Yen, Dehui Wan, and co-workers develop a paper-based, portable surface-enhanced Raman spectroscopy (SERS) detection platform with an extremely high Raman enhancement factor and detectability at sub-femtomolar concentrations, even when operated with a portable NIR Raman spectrometer. The fabrication process involves depositing abundant and dense gold nanopearls with narrow gap distances directly onto fluorosilane-modified cellulose fibers through simple thermal evaporation. This scalable and portable fibrous SERS substrate has the potential for practical on-site detection in biofluid analysis, point-of-care diagnostics, and precision medicine.
