QCM study of the adsorption of polyelectrolyte covered mesoporous TiO2 nanocontainers on SAM modified Au surfaces

► Surface layer, ionic strength and pH have strong effect on NCs deposition process. ► Surface charges enable adsorption at acidic pH regardless ionic strength. ► Deposition at higher pH strongly depends on salt concentration. ► The Debye length becomes thinner at the high ionic strength. ► The particle can approach the surface close enough that deposition can take place.
