Perles magnétiques PEG-Fe3O4: Ouvrant la voie à une nouvelle ère de médecine de précision et de gestion environnementale

Introduction

PEG-Fe₃O₄ magnetic beads represent an innovative functional material that seamlessly integrates a superparamagnetic iron oxide (Fe₃O₄) core with a highly biocompatible polyethylene glycol (CHEVILLE) shell through advanced nanotechnology. Their unique multifunctional properties make them an ideal platform material for both biomedical and environmental applications.
