Orthobond’s core technology centers on the development of a system of phosphonic acid linker molecules and proprietary methods to attach them to substrates. Originally developed as a method to modify titanium and titanium alloys, the technology has been expanded to encompass polymeric surfaces as well.


Shown above is a self-assembled monolayer of phosphonic acid (SAMP) array both as a graphic representation and as a real image from atomic force microscopy. Phosphonic acid linkers provide many advantages for metallic surface modification:

  • Covalent Attachment
  • Hydrolytically Stable
  • Strong Bonds
  • Nanometer Scale Coatings
  • Resistant to Oxidation
  • Versatile Functionalization
  • Easy Customization
