Detection of NH stretching signals from the monolayers of amino acid amphiphiles at the air-water interface and change of hydrogen bond depending on metal ion in the sub phase: infrared reflection-absorption spectroscopy

Article Abstract:

Using the infrared reflection-absorption spectroscopy (IRRAS) technique, the NH-stretching bands are observed from N-octadecanoyl-L-alanine monolayers at the air-water interface. The hydrogen bond existed in the monolayers undergoes an obvious change in the presence of metal ions in the subphase.

Supramolecular architectures of streptavidin on biotinylated self-assembled monolayers: tracking biomolecular reorganization after bioconjunction

Article Abstract:

The supramolecular bioconjugation of streptavidin (SAv) on biotinylated self-assembled monolayers is analyzed, using the quartz crystal microbalance method. The results have shown that the reorganization is an Ostwald ripening-type process, which is described by the Lifshitz-Slyozov law.
