Notes:
Fluorescence microscopy is a sensitive and nondestructive optical method to directly study the properties of monolayers at the gas/water interface and to control their transfer on solid substrates. The method requires only small amounts (≤1 mol %) of fluorescent probe molecules for optical detection. In this article, an integrated system for optical investigations on mono- and multilayer structures is described. The experimental equipment consists of a monolayer trough, a deposition unit to built-up ordered layers and a fluorescence microscopic attachment. The modular construction allows the use of any desired trough design for the monolayer investigations. The system comprises video-assisted microscopy to observe and analyze dynamic nucleation processes taking place during phase transitions on liquid and solid substrates. Using the spatial two-dimensional digital image signal, kinetic studies can be performed.
