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

Author

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.

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.

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.

Abstract

The article addresses on the transmission of metal films with arrays of subwavelength holes implicating for sensors and enhanced surface spectroscopy. The paper describes the basics of the type of surface plasmons-mediated transmission. It explains how the properties move into the infrared region. It also includes the discussion of the stacks of mesh and the potential for sensors. A figure shows the electron microscopy images of the nickel mesh and the structure of the arrays revealing an open area.
