This technique allows the fabrication of holographic sensors that display improved versatility and scalability. The platform utilizes an effi cient approach to produce off-axis chemical-stimuli responsive holo-graphic sensors with a large, reversible narrow-band tunability, using metallic nanoparticles that can be organized in density-concentrated 3D regions. The present work employs a hologram fabricated by laser ablation comprising of a functionalized hydrophilic host polymer. The optical…
