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.
对具有超精度和对药物释放的控制的更有效的药物输送策略的需求,导致了更复杂的药物释放系统作为传统临床治疗的有前途的替代方案的发展。这些新策略的种子探索了一种有希望的特性,以克服传统疗法的固有问题。任何药物输送系统的主要挑战之一是引入对输送系统的完整视图。在本文中,我们旨在阐明电合成 ATN@DNA 核壳样结构作为模型系统的理论概念证明。因此,我们提出了一种分形动力学模型(非指数模型),该模型考虑了时变扩散系数的概念,该模型是使用 COMSOL Multiphysics 的数值方法开发的。此外,我们在这里提出了一种广义分数动力学模型,根据 tempered 分数算子的概念,这导致了释放过程的更好特征化记忆特性。此外,分数模型与分形动力学模型进行了比较,两者都对呈现异常动力学的药物释放过程提供了很好的描述。分形和分数动力学模型的解也成功地与我们的实际释放结果拟合。
