“…This spectra is consistent with that of the solid indicating multilayer formation. 45 The results of the deposition on iron and stainless steel 316L were collected and the data are presented in Table 1. Ordered and stable multilayers were formed on all surfaces.…”

Analysis and confirmation of monolayer film thickness on metal oxide surfaces has proven to be challenging. XPS and AFM have been used to investigate the monolayer formation. However, these techniques are difficult to access and/or determine the composition of the organic molecules on the surfaces. Here we demonstrate the ability of MALDI-TOF to characterize long alkyl chain phosphonic acid molecules in thin films on titanium, iron and stainless steel. These systems are known to be stable, strongly adhered films. The thin films were characterized by IR, AFM, contact angle measurements and the results were confirmed by MALDI-TOF. Moreover, the MALDI-TOF was used to differentiate between mono-and multilayers on planar surfaces.

“…Such functional groups also revealed the ability to chemically link to metal oxide surfaces [16,[20][21][22]. So, modifying the implant surface through phosphonic groups appears to be a way to promote a strong adhesion between the implant surface and bone tissue.…”

“…Recently, however molecular layers on metal oxide such as TiO 2 and ZrO 2 have also been of interest for applications such as dye-sensitized solar cells and photocatalysis [6,7,8,9,10]. Methods commonly employed include the use of carboxylate groups chelating to the undercoordinated surface metal atoms, silane chemistry, and phosphonic acids [11,12,13].…”

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 TiO2 in nanocrystalline thin films and as single‐crystal anatase(001) epitaxial films grown on SrTiO3(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)
