1. A method comprisingadministering to a subject a plurality of magneto-electric nanoparticles (MENP) having (i) a coating on at least a portion of the MENP surface, said coating one or more of glycerol monooleate, poly L-lysine and polyethylene glycol, and (ii) a drug associated with the MENP through an ionic bond;
- andapplying a magnetic field to the subject to weaken the ionic bond thereby releasing at least a portion of the drug from the MENP.
