Anomalous Kinetic Study of Atenolol Release from ATN@DNA a Core-shell Like Structure

The need for more efficient drug delivery strategies with ultraprecision and control over the release of drugs has led to the growth of more sophisticated drug-releasing systems as a promising alternative to conventional clinical therapies. This new seed of strategies has explored an encouraging property to overcome the inherent problems of traditional therapies. One of the major challenges for any drug delivery system is the introduction of a complete view of the delivery system. In this article, we intend to elucidate the theoretical proof of concept of the electrosynthesis ATN@DNA core-shell like structure as a model system. Therefore, we present a fractal kinetic model (non-exponential model) taking into consideration the concept of time-dependent diffusion coefficient, which was developed using a numerical method with the help of COMSOL Multiphysics. In addition to that, we present here a general fractional kinetic model in sense of the tempered fractional operator, which leads to better characterized memory properties of the release process. Also, the fractional model is compared with the fractal kinetic model and both offer a good description of drug release processes that present anomalous kinetics. The solutions of the fractal and fractional kinetic models are also fitted successfully with our real-release results.
