Present developments in the field of bioscience will profit from the fabrication of multilayer films of polyelectrolytes on colloids as well as of nano- and microsized capsules. The single particle light-scattering technique is suitable for process control. This paper describes the mode of operation and efficiency of a laboratory-built single particle light-scattering photometer, which opens up new possibilities in applications, especially in the field of bioscience. This has been achieved by improving the measurement capabilities of organic particle sizes near 100 nm and precision of thickness changes of about 0.5 nm. Besides the classic applications, such as particle size distribution measurements at high resolution and the coagulation kinetics of colloids, the measurement of the layer-by-layer polyelectrolyte adsorption at colloid particle surfaces and the fabrication of colloidal carriers is introduced. The described method is also a precise method for controlling the removal of the latex core to obtain multilayer microcapsules. (C) 2004 Elsevier Inc. All rights reserved.
