The adhesion of colloidal gold on membranes was examined
with an electron microscope with protein on the membrane, on
the colloidal particles and present on both membrane and particles.
The conditions for best adhesion were determined. Quantitative
measurements were caNied out using adhesion to the membrane
to monitor diffusion, centrifugation and electrophoresis of colloidal
particles. Electrophoresis in a centrifugal field was used as a nul
method to determine the charge on the colloidal particle.
