Fast microwave-assisted conjugation of magnetic nanoparticles with carboxylates of biological interest

Abstract

A new technique of surface modification of nanoparticles (Fe₃O₄-NP) with carboxylates of biological interest has been developed with a microwave-assisted heating method. This two-step technique reduces the reaction time to 15 min (for each step) and increases the number of substituents to 2300 molecules compared to traditional methods with a maximum of 440 molecules.
