Gold Coatings for Spectroscopy

In the world of scientific research, spectroscopy is a pivotal technique that allows scientists to analyze material properties and compositions with unparalleled precision. Among the materials utilized in this field, gold-thin films stand out for their remarkable ability to enhance spectroscopic techniques. This post delves into the unique properties of gold-thin films, their applications in various spectroscopy methods, and the benefits they bring to scientific research.

What are Gold Thin Films?

Gold-thin films are layers of gold deposited onto a substrate such as glass or silicon, creating a film of only a few nanometers to several micrometers thick. These films are prized for their excellent electrical conductivity, chemical stability, and unique optical properties. At Platypus Technologies, we specialize in creating customized gold-thin films tailored to meet the specific needs of researchers and engineers, ensuring that every application harnesses the full potential of this remarkable material.

Applications of Gold-Thin Films in Spectroscopy

Surface Plasmon Resonance (SPR)

SPR is a powerful technique used to study molecular interactions in real-time, without the need for labeling. Gold-thin films are integral to SPR sensors, where their ability to support surface plasmons enhances the sensitivity and specificity of the technique, making it invaluable in biochemical and pharmaceutical research.
