Characterization of a Covalently Bound Phospholipid on a Graphite Substrate by X-ray Photoelectron Spectroscopy and Scanning Tunneling Microscopy

A novel method is reported for the covalent binding of a phospholipid to an oxidized graphite substrate using the surface carboxyl functions. The resulting surface is characterized by X-ray photoelectron spectroscopy (XPS), reflectance FTIR, and scanning tunneling microscopy (STM). © 1989, American Chemical Society. All rights reserved.
