Nanoplasmonic Sensing for Nanomaterials Science

Scalable Fabrication of Quasi-One-Dimensional Gold Nanoribbons for Plasmonic Sensing

“…Apart from increasing platform stability, dielectric coatings, e.g., In 2 O 3 , enable indirect nanoplasmonic sensing and thus, characterization of interactions of biomolecules with a variety of materials beyond Au. 38,39 This approach has paved the way for studies involving biomolecule interactions with silicon and TiO 2 surfaces (using other nanostructures as optical transducers). [40][41][42][43][44][45] Here, arrays were fabricated on clear glass substrates to enable optical measurements in transmission mode.…”

“…The slope (i.e., from baseline to plateau) can provide a series of quantitative information ( Figure S7), such as initial rate and the number of intermediate steps, in any, involved in the biomolecular interaction, as we reported previously. 29,38,41 Plasmonic features showed different responses to lipid vesicle adsorption with respect to their bulk sensitivities, suggesting a mismatch between bulk and surface sensitivities of the dips and peaks of the Au nanoribbon arrays.…”
