“…In fitting the S 2p 3/2 and S 2p 1/2 doublet, as shown in Figure , a spin−orbit splitting of 1.2 eV and a peak area ratio of 2 can be attained. In the freshly prepared Au/TiO 2 catalyst, the peaks for the S 2p 3/2 and S 2p 1/2 doublet (162.0 and 163.2 eV) can be assigned to the S−Au bond as reported in the literature. − Clearly, both thiol ends from DDT and MPA molecules can contribute to the S−Au formation . After 9 h of photoreactions using this catalyst, consistent with our FTIR results, it is found that both peaks show a significant decrease in intensity.…”

In this work, we report that presynthesized metallic nanoparticles (such as gold nanoparticles), rather than on-site growing ones that are prepared under thermally or photochemically activated conditions, can be “impregnated” uniformly onto premade oxide supports with organic interconnects which have bifunctional groups. Methodic features of this general technique have been demonstrated using a model metal−oxide system, Au/TiO2 (TiO2 in anatase phase) catalyst, in the photodegradation of organic compounds (e.g., methyl orange). On the basis of our investigations with a range of analytical techniques, it has been further found that, if desired, permanent engagement and direct contact between the supported metals and oxide carriers can also be achieved with additional heat treatments. In principle, other oxide-supported metal catalysts can also be fabricated at low temperatures through these types of self-assembling routes.

In this paper, we report a novel biological fluorescent probe for the diagnosis of human ovarian tumor based on sandwiched TiO(2) nanoparticles. The fluorescence nanoparticles consist of a fluorescent molecule, tetramethyl rhodamine isothiocyanate (TRITC), sandwiched between titanium dioxide (TiO(2)) nanoparticles and nano-gold via reacting with each other. The antibodies HER2, labeled on the surface of the biofluorescence nanoparticles, have granted nanoparticles the privilege of aiming at peculiar tumor antigen. The specificity of antibody-nanoparticles interacting with cells was characterized by Laser Scanning Confocal Microscope. The results showed that these sandwiched nanoparticles were innocuous and stable, and the method offered potential advantages of sensitivity and simplicity due to high combing efficiency between nanoparticles and cells and provided an alternative method for the diagnosis of human ovarian tumor (HOT).
