Iron phosphide nanoparticles as a pH-responsive T1 contrast agent for magnetic resonance tumor imaging†
Abstract
In this work, the potential of FeP nanoparticles as a pH-responsive T1 contrast agent was investigated. The FeP nanoparticles have good biocompatibility and can significantly amplify T1 magnetic resonance signals in response to the acidic microenvironment of solid tumors, holding great promise in serving as an acid-activatable T1 contrast agent for tumor imaging.
