The Programmable Nature of Drug-Polymer Systems and Its Implications.

In our work, we use the multifractal motion theory to apply a multifractal state density conservation law to the polymer-drug release process. This law is specific to the transition from multifractal to nonmultifractal curves corresponding to the polymer-drug release processes. A multifractal diffusion-type law was obtained, which describes the cyclic drug release dynamics until the polymer matrix is fully degraded. The polymer-drug system reveals a programmable nature due to its complex part and scale resolution dependence.
