Midatech’s proprietary platform is based on a three-layer gold nanoparticle (GNP) offering significant advantages and flexibility.

Midatech’s GNPs are produced using a one-step self-assembling synthesis of consistently sized, water soluble, stable, passivated nanoparticles. Broadly, this proprietary chemistry yields a wide variety of covalently bound bio-active molecules with precise stoichiometry. The flexibility of the chemistry results in a wide repertoire of nanomedicines for future development.

At sizes less than 3.5 nanometers in diameter, GNPs are well suited for movement into cells through the walls of blood vessels and across the blood-brain barrier. Critically, the size of the GNPs fosters their elimination through kidney and biliary clearance. Pre-clinical studies to date confirm that there is no accumulation of GNPs in the kidney and no evidence of toxicity. GNPs have also been shown to be safe in a Phase I human clinical study.
