Abstract

Water-dispersible biotin-modified biofunctional ferromagnetic L1o FePt nanoparticles (NPs) have been synthesized by using a silica nanoreactor strategy. The coercivity field of the NPs was 16 kOe at room temperature, with a particle size of around 5.19 nm. Biotin-coated L1o FePt NPs were biocompatible in an aqueous environment and show site-specific interactions with avidin compounds that could potentially yield a new magnetic material for biological applications, such as for biomolecular recognition.
