Abstract

Nanocrystalline NaY zeolite is a prospective material for a variety of biomedical applications, such as drug and gene delivery, as well as magnetic resonance imaging. The stability of the zeolite framework is necessary to assure safety of the material in the human body. The NaY zeolite samples (27 and 53 nm particles) were synthesized and functionalized with chloropropyl (CP) groups and polyethyleneimine (PEI) polymer. The stability of the zeolite samples at pH 7.4 for up to 10 days was studied using ICP-OES for elemental analysis. The CP and PEI-functionalized NaY showed a higher stability at pH 7.4 than the parent zeolite samples because the zeolite framework is protected by the organic moieties.
