Hydroxyapatite nanocomposites

Pure Ti02 was recently reported to be active in the disinfection of water contaminated by spores of the type Fusarium solani [142], Bacillus anthracis [143], or Cryptosporidium parvum oocysts [144], or when supported as nanocomposites on zeolite H(i for E. coli deactivation [145], and it found applications in water treatment as a replacement for chlorine. Ag-Ti02 immobilized systems were used for inactivation of bacteria, coupling the visible light response of the system and the strong bactericidal effect of Ag [146]. Silver was deposited on hydroxyapatite to form nanocomposites with a high capacity for bacterial adsorption and inactivation [147], or used for airborne bacterial remediation in indoor air [148],... [Pg.107]

The average size of magnetite and hydroxyapatite crystallites was calculated in accordance to (311) and (002) X-ray diffraction peaks, respectively, with the use of the Scherrer formula. The thickness of the hydroxyapatite layer on the surface of magnetite nanoparticles was 4 nm, which was evaluated by the area ratio of Fe2p- and Fe3p-lines (studied by X-ray photoelectronic spectroscopy) and the increase in the Fe304/HA nanocomposite mass ( 30%). [Pg.312]

Immobilizcition of antibodies at the surface of nanocomposites magnetite—polyacrylamide, magnetite— -aminopropylsiloxane, and magnetite-hydroxyapatite was carried out by the techniques described above. [Pg.321]
