speciality

We specialize in the development of chemically modified nanomaterials into drugs. These materials hold great promise for improving healthcare outcomes and greatly reducing cost. We are a leader in the field as a developer of such compounds (with over 40 peer-reviewed publications and 3 journal covers on applications of functionalized nanomaterials). In addition to nanomaterial development, we specialize in the development of animal models of cancer, kidney disease, and toxic metal exposure, which are necessary for the in vivo evaluation of our nanomaterials. Our company’s strength is in nanomaterial research and expertise that will lead to novel pharmaceutical products.
