Fluorescent TLC Plates via Atomic Layer Deposition ID: 2014-031

This technology revolutionizes thin-layer chromatography by introducing fluorescence, significantly enhancing detection under UV light.

Technology Overview

This invention discloses a method for fabricating fluorescent thin-layer chromatography (TLC) plates using atomic layer deposition (ALD) of zinc oxide (ZnO). It incorporates a unique process that includes photolithographic patterning, deposition of iron and alumina, and the growth of carbon nanotubes (CNTs) as a scaffold for achieving fluorescence. The method details the use of various coating materials, such as silicon nitride and ZnO, on CNTs to enhance fluorescence capabilities, employing techniques like low-pressure chemical vapor deposition (LPCVD) and ALD, supported by analysis methods including XPS and XRD.
