We have monitored the interactions of DNA strands immobilized on silica at the buried solid/liquid interface using vibrational sum frequency generation. We find that the nucleobases exhibit net order even prior to hybridization for immobilized single

Understanding the influence of immobilization is key to advancing efforts in green chemistry based on supported catalyst materials. The binding of a model reactant 4-nitroacetophenone with amino and ureido organocatalytic monolayers has been investig

The Cu(I) -catalyzed 1,3-dipolar azide-alkyne cycloaddition (CuAAC) has arisen as one of the most useful chemical transformations for introducing complexity onto surfaces and materials owing to its functional-group tolerance and high yield. However,

Using second harmonic generation and sum frequency generation spectroscopy, we monitor the influence of sodium and potassium halides on acid–base processes at the negatively charged silica/aqueous electrolyte interface. We find that the two types o

Using nonresonant second harmonic generation spectroscopy, we have monitored the change in surface charge density of the silica/water interface over a broad pH range in the presence of different alkali chlorides. Planar silica is known to possess two
