Zeolite-based biomaterials for biomedical application: A review

This review focuses on the latest reports of the use of zeolites, natural as well as synthetic, as biomedical materials. Discussion on biocompatibility, non-toxicity, zeolite for drug delivery materials, zeolite for bone implants and implant coatings, and the mechanical properties of polymer-zeolite composites are included. The section on the interaction between body tissues and zeolite-based biomaterials focuses on their biocompatibility, non-toxicity, and bioactivity. The next section concerns drug delivering biomaterials. Including delivery of a controlled drug, ionic removal, and synthesized drug delivering materials. The final section concern bone graft substitutes and implant-coating to improve corrosion resistance and osteointegration. The implant material system discussed in a further section is an investigation of the mechanical properties of high-density polyethylene(HDPE)-zeolite composites developed as skull bone implant materials.
