Numerical Studies on Magnetic Driven Targeted Drug Delivery in Human Vasculature

Magnetic driven targeted drug delivery (TDD) involves the manipulation of magnetic drug carriers, such as nano/micro particles or bubbles, within the body using external magnetic fields to precisely reach the intended target location. This method is utilized in treating severe illnesses like cancerous tumors and nervous disorders, offering higher efficacy with reduced drug dosages and side effects. While numerous studies have simulated magnetic driven TDD, comprehensive reviews remain scarce. This article presents an extensive review of computational/numerical work done on magnetic driven TDD utilizing both microbubbles and non-bubbles (nano/micro particles) within human vasculature and lung airways. The study aims to analyze the drug delivery problem from physical and numerical perspectives. Key highlights include artery wall models (rigid, flexible, or porous), models of force acting on particles, relevant governing equations, discussions on parameters of interest and their effects on drug delivery efficacy. Finally, the article briefly outlines common trends observed in magnetic driven TDD problems and their underlying physical principles.
