Molecular Manipulation for Plasmonic Applications

About this Research Topic

A localized surface plasmon is a hybrid surface mode of electrons and photons that, upon resonant light illumination, can be excited on the surface of metal nanostructures with the localized and enhanced electromagnetic field. Excitation of the localized surface plasmon is used to amplify scattering and absorption of the incident light by the nanostructures. The former is usually applied to surface-enhanced spectroscopies that employ the enhanced electromagnetic field to excite molecules adsorbed on the nanostructure surface. The latter decays to hot electrons that can exchange with the adsorbed molecules for plasmon-mediated photocatalysis. Therefore, the efficient use of the plasmonic phenomena relies on how to place the molecule of interest near or in contact with the plasmonic surface in order to allow excitation or electron transfer. One typical example is hydrophobic plasmonic nanopillars that can concentrate solvents from a droplet of solution for surface-enhanced Raman spectroscopy.

When the plasmonic applications advance to be practical in, for example, biosensing in serum, selective capture of target molecules in a complex environment is critical to obtain required signals over background noise. On the other hand, emerging fundamental studies such as single-molecule analysis and catalysis require small plasmonic nanostructures to squeeze light energy in a nanoscale space that is usually too small to allow diffusive access of the molecules. Therefore, molecular manipulation for plasmonic applications has become increasingly important. This Research Topic aims to collect recent trends of molecular manipulations that can be associated with the plasmonic nanostructures or devices to improve performance for a wide range of plasmon-mediated applications. We welcome submissions that employ various molecular manipulation methods such as optical trapping, magnetic tweezering, dielectrophoretic trapping, hydrophobic concentration, micro-/nanofluidic confinement, and immunoassay.

We invite submissions of Original Research, Reviews and Mini Reviews that explore, among other areas, the following research areas:

• Surface plasmon resonance sensors,
• Surface-enhanced Raman spectroscopy,
• Surface-enhanced fluorescence,
• Surface-enhanced infrared spectroscopy,
• Plasmonic photochemistry,
• Plasmonic photocatalysis,
• Plasmon-mediated phototherapy.


Keywords: Plasmonics, Surface-enhanced spectroscopy, Photochemistry, Photocatalysis, Phototherapy


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
