Abstract Previous work has shown that organic alkenes will graft to covalent semiconductors such as diamond and silicon. Here, we demonstrate that organic alkenes can be grafted to the surfaces of metal oxide semiconductors, including TiO 2 in nanocrystalline thin films and as single‐crystal anatase(001) epitaxial films grown on SrTiO 3 (001) substrates. The resulting layers can be used as a starting point for linking biomolecules such as DNA to metal oxide surfaces. Initial results are presented showing that this chemistry can also be applied to graft molecular layers to zirconium oxide thin films. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
