Abstrakt     The increase in the surface to volume ratio at the collapse transition of gels can be exploited to allow for an NMR determination of fractal dimension of the gel surface in the liquid state where this quantity is hard to measure with other techniques. The measured quantities are the ratio between the spin-lattice and spin-spin relaxation times T1/T2 of the liquid component and the ratio of the masses or volumes of the gel before and after the collapse transition. The technique has been used to determine the surface fractal dimension of a blood plasma gel.
