摘要：

The adsorption on a gold surface of 5-50-nm silica particles in solution has been studied by the piezoelectric quartz crystal microbalance technique. The parameters of the solution where a reproducible layer by layer deposition is possible have been characterized. The uptake depends strongly on the ionic strength of the solution, but only weakly on the particle size or concentration. The strong dependence on ionic strength is attributed to electrostatic screening. (C) 1995 Academic Press, Inc.
