By carrying out ~1H spin-diffusion experiments,the domain sizes of DNA in the complexes were determined.The domain size of DNA is found to decrease greatly when the N/P ratio changes from 0.5 to 3 and changes only slightly with further increase of the N/P ratio.After making a thorough analysis and discussion on drug control release and gene delivery systems with general NMR techniques,we presents a method of 1D PFG NMR technique to realize quick observation on the Mw change of polymer during its degradation process.Moreover,according to the inverse Laplace transformation theory and based on a function of diffusivity distribution of polymer in solution,2D PFG NMR technique is developed to measure the Mw distribution of polymer.Combined with Monte Carlo simulation,the degradation mechanism can be figured out.
