Assessment of the morphology of mixed SAMs on Au nanoparticles using a fluorescent probe.
The distribution of thiols in mixed SAMs can be determined in a straightforward manner from spectrophotometric titrations using a fluorescent probe. A plot of saturation concentration as a function of mole fraction provides information on the number of headgroups involved in binding.
