Fluorescence correlation spectroscopy is a method to study the self-diffusion of fluorescence labeled molecules. The detection volume is very small ( 1 µm3), and the measurements are carried out on the basis of very few molecules in the detection volume. We present results on the diffusion of fluorescence labeled poly(methyloxazolin) polymers in aqueous solution as a function of concentration and degree of polymerization. Additionally the aggregation behavior of a an amphiphilic poly(methyloxazoline) poly(nonyloxazoline) diblock copolymer have been investigated in aqueous solution, along with the influence of the position of the fluorescence label.
