CORE-MULTISHELL NANOSTRUCTURED MODELS FOR NANO-BIOMEDICAL AND NANO-BIOPHARMACEUTICAL APPLICATION

The main advantage of the theoretical approach is essential knowledge of the mechanisms that allow us to comprehend the experimental conditions that we have to fulfill to achieve the desired results. Based on our research in ultrathin crystal structures, superlattices, Q-wires, and Q-dots, we examine materials that can act as carriers for medicines and tagged substances. We established a shell-model of ultrathin molecular crystals and investigated their dielectric, particularly optic characteristics, using a two-time dependent Green's function method tailored for ultrathin crystalline structures. Our findings reveal specific resonant absorptions in these structures, dependent on crystal layer position and parameter values at shell-structure boundaries. This demonstrates that the outer environment of the film affects the fundamental properties of a nano film, allowing for direct control over its basic physical properties—a form of nano-engineering. We analyze nanomaterials' application in biomedicine, discussing recent achievements in basic and clinical nanomedicine. While the full potential of nanomedicine may take years or decades to realize, advances in drug delivery, diagnosis, and nanotechnology-related drug development are changing the medical landscape. Concepts like site-specific targeted drug delivery and personalized medicines are emerging. This paper also analyzes changes in the basic physical properties of spherical-shaped nanoparticles with multiple (nano)layers and their potential medical applications. We present a review of our current achievements in the theoretical physics of ultrathin films and potential applications in nano pharmacy.
