Controlling the passage of light through metal microchannels by nanocoatings of phospholipids

Article Abstract:

The molecular details of the assembly (DPPC phospholipid monolayer/bilayer on a hexadecanethiol monolayer on a copper- or nickel-coated microarray) are determined using the infrared, surface-plasmon-mediated, extraordinary transmission of the metal microarrays. Infrared absorption spectra with greatly enhanced absorptions by comparison to literature are recorded and used as a diagnostic for the phase composition, and molecular geometry of these nanocoatings.

Use of the extraordinary infrared transmission of metallic subwavelength arrays to study the catalyzed reaction of methanol to formaldehyde on copper oxide

Article Abstract:

The preparation of a commercial nickel mesh coated with copper in order to reduce the metallic micro- and nanoarrays of subwavelength holes size is explained. Reduction of hole sizes enhances surface plasmons (SPs) lifetime and help to study the catalytic process on copper (Cu) surface via zero-order FTIR transmission spectra.

Accessing surface plasmons with Ni microarrays for enhanced IR absorption by monolayers

Article Abstract:

Surface plasmons were accessed with mid-IR light using zeroth-order FTIR transmission spectra. It is reported that these can be used in sensitive detection schemes.
