The invention belongs to the technical field of
biomedical engineering, and relates to a DLS time-varying autocorrelation inversion
drug diffusion coefficient method, which comprises the following steps: constructing a structure-enhanced time-varying autocorrelation function
data set through overlapping time window division,
standard time-varying autocorrelation function calculation and correction factor fusion of structural sensitive parameter derivation; then, a dynamic parameterized
physical model related to hydrogel structure parameters is constructed based on the
diffusion theory,
diffusion coefficients are dynamically adjusted along with structure evolution, a theoretical autocorrelation function sequence with matched dimensions is generated at the same time, and then, through the trained intelligent inversion model, regularization optimization and
uncertainty estimation are combined, so that a dynamic self-
correlation function sequence of the hydrogel structure parameters is obtained. According to the method, the optimal time-varying diffusion coefficient is accurately inverted, and finally, through comparison of theoretical and actual
drug release curves, dynamic
error feedback adjustment and energy efficiency evaluation, the accuracy of diffusion coefficient inversion and release efficiency evaluation is ensured, and accurate data support is provided for hydrogel
drug carrier formula optimization, release
kinetics analysis and clinical administration scheme design.
