About this document
AFM Study of Carboxylic Acid SAMs by amandasheza is a document available to read on EtoBox.
This study employs atomic force microscopy (AFM) to investigate the surface acid-base properties of carboxylic acid-terminated self-assembled monolayers (SAMs) on gold substrates. The research measures forces between a silica probe and the SAM in varying pH KCl solutions, revealing that the interaction is significantly influenced by pH and allows for the determination of surface electrostatic potentials and pKa values. The findings provide insights into the behavior of surface-confined molecules and demonst
