Characterization of organic monolayers on diamond surface by infrared absorption spectroscopy

Project goals

Project is focused on basic research in the preparation and detection of organic monolayers on the nanodiamond (NCD) with a defined surface morphology in order to achieve continuous and stable coverage for biosensor applications. Functionalization of nanodiamond surface will be carried out chemically, photochemically and from gas phase using thermal and plasma activated processes. The weak optical absorption of molecular monolayers on NCD films and functional groups on diamond nanoparticles will be detected by highly sensitive methods of the infrared optical absorption spectroscopy developed during the project. Will be modelled the impact of angle of incidence and the polarization of light on reflective spectra of NCD films deposited on metallic substrates in order to increase the optical reflectivity and increase sensitivity of the grazing angle reflectance method. Modelled results will be compared with measured spectra. NCD films will be grown on Ge prism to develop a reliable ATR prism as a powerful alternative for the study of functionalized diamond surfaces.

    Charakterizace organických monovrstev na diamantovém povrchu metodou infračervené absorpční spektroskopie

  • Annotation in Czech

    Projekt je zaměřen na základní výzkum v oblasti přípravy a detekce monovrstev organických látek na nanodiamantovém (NCD) povrchu s definovanou morfologií s cílem dosáhnout souvislé a stabilní pokrytí pro biosenzorické aplikace. Funkcionalizace nanodiamantových povrchů bude realizována chemicky, fotochemicky a z plynné fáze termálně i plasmaticky aktivovanými procesy. Funkční skupiny povrchově vázaných molekulárních monovrstev budou detekovány vysoce citlivými metodami infračervené optické spektroskopie,vyvinutými v rámci předkládaného projektu. Bude modelován vliv úhlu dopadu a polarizace světla na reflexní spektra NCD vrstev deponovaných na kovových podložkách s účelem zvýšení jejich optické odrazivosti a zvýšení citlivosti GAR (grazing angle refelctance) metody. Výsledky modelování budou porovnány s naměřenými spektry. NCD vrstvy budou také nadeponovány na Ge hranolu s účelem vyvinout spolehlivý ATR hranol jako silná alternativa pro studium funkcionalizovaných diamantových povrchů.

  • Project results evaluation

    Sensitive infrared optical spectroscopic methods for measurements of functional groups of molecular monolayers on the diamond surface were developed and new knowledge in preparing surfaces functionalized nanodiamonds with specific surface and optical properties for biosensor applications gained. The results were published in 6 papers (5 Jimp, 1 Jneimp) in international journals.
