The coaggregating tendencies of the culprits of arteriosclerosis, the cholesteryl esters (CE-n’s), have been investigated in the 40:60 V/V (Φ= 0.40) dioxane (DX)-H2O system, by using decyl pyrenyl ketone (Py-11) as the fluorescence probe. The fluorescence intensity of Py-11 decreases when coaggregation occurs between CE-n and Py-11, because of the low polarity of the microenviroment of the coaggregates. The order of the coaggregating tendencies obtained from the fluorescence data is in full agreement with that from the kinetic method, i.e., CE-ol, CE-in > CE-12 > CE-8 > CE-18 > CE-0.
