Magnetic targeting via external magnetic field

Magnetic targeting via external magnetic field" is not a molecular target, receptor, enzyme, transporter, or similar biological entity. Instead, it refers to a **physical method** used in biomedical applications where an external magnet is employed to guide and concentrate **magnetic nanoparticles**—often loaded with drugs—to specific sites within the body. This approach aims to enhance local drug concentration at disease sites such as tumors while minimizing systemic exposure. The technique relies on the interaction between externally applied magnetic fields and superparamagnetic particles like iron oxide nanoparticles. While effective near surface tissues using static magnets, achieving deep tissue focusing remains challenging due to physical limitations described by Earnshaw’s theorem; recent research explores dynamic pulsed fields as a potential solution[1][3]. This entry does not correspond to any canonical molecular target and should be flagged as incorrect if used in that context.
