Assessment of Drug Flow Rate in Skin Cancer Therapy for Enhancing the Drug Delivery System

Area of Science:

• Biomedical Engineering
• Oncology
• Pharmacology

Background:

• Skin cancer poses a significant clinical challenge, necessitating improved early detection and treatment methods.
• Conventional drug delivery for skin conditions is often limited by the inability of medications to effectively cross cellular barriers.
• Existing diagnostic and therapeutic modalities for skin tumors have limitations, highlighting the need for innovative approaches.

Purpose of the Study:

• To develop a novel electrical analogue model of the skin, encompassing its distinct physiological layers.
• To mathematically model the electrical network of the skin for simulation purposes.
• To analyze drug absorption and diffusion dynamics within different skin layers to optimize therapeutic strategies.

Main Methods:

• Development of a mathematical model representing the electrical properties of skin layers (dermis, subcutaneous tissue, muscle, bone).
• Conducting simulation studies to analyze the electrical response and drug interaction within these modeled skin layers.
• Incorporating a conventional controller to minimize drug diffusion rates and enhance absorption.

Main Results:

• Simulation results demonstrate that cells within each skin layer absorb and release drugs to adjacent layers.
• The study quantifies the absorption and diffusion capacities of various skin layers.
• The implemented controller effectively modulated drug diffusion, showing a contrast in absorption and diffusion characteristics.

Conclusions:

• The developed electrical analogue of skin provides a valuable tool for understanding drug transport mechanisms.
• This model can inform the design of more effective drug delivery systems for treating skin conditions, including cancer.
• Optimizing drug absorption and minimizing diffusion through controlled delivery holds promise for enhanced therapeutic outcomes in skin cancer treatment.
