In Situ Electrodeposition of Gold Nanostructures in 3D Ultra‐Thin Hydrogel Skins for Direct Molecular Detection in Complex Mixtures with High Sensitivity (Laser Photonics Rev. 15(12)/2021)

Au–Hydrogel Nanocomposites In article number 2100316, Sung-Gyu Park and co-workers develop a new Auhydrogel nanocomposite structure in situ Raman measurements system. The ultra-thin hydrogel skin layer on the Au nanopillar arrays selectively allows infusion of small target molecules. materials monitoring techniques enable rapid affordable SERS-based on-site analysis point-of-care testing.
