Biomaterials functionalized with magnetic nanoparticles for tissue engineering: Between advantages and challenges

The integration of magnetic nanoparticles (MNPs) into biomaterials offers exciting opportunities for tissue engineering as they enable better control over cell guidance, release of bioactive factors and tissue maturation. Despite their potential, challenges such as the heterogeneity of MNPs, their cytotoxicity and the need for precise control of MNP`s properties hinder their widespread application. Overcoming these challenges will require new interdisciplinary efforts and technological advances, including the development of mathematical tools and additional elaborations to ensure the biocompatibility of MNPs.
