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

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.
