Abstract
In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to acidified water vapor or immersion in a concentrated acid bath (e.g., HCl and methanol). At least a portion of the elongated nanostructures may be removed after being coated. Embodiments for TLC plates and related methods are also disclosed.
