چکیده

A novel and simple method to prepare well dispersed single-walled carbon nanotubes with strong visible fluorescence in water is reported. The visible fluorescence was found to be responsive to pH value and metal ions, and tunable emission ability of oxidized SWCNTs depending on the excitation wavelength and a novel self-excitation and emission process were found.

Combing DNAzyme with single-walled carbon nanotubes for detection of Pb(II) in water.

A sensitive and simple assay for the detection of Pb(2+) in aqueous solutions is reported. It takes advantage of the high affinity between single-stranded DNA (ssDNA) and single-walled carbon nanotubes (SWCNT) as well as the capability of SWCNT in fluorescence quenching. Lead(II) catalyzes the cleavage of a fluorescently labeled DNA substrate by a DNAzyme, which releases the single-stranded pro...

Visible fluorescence induced by the metal semiconductor transition in composites of carbon nanotubes with noble metal nanoparticles.

We show that single-walled carbon nanotube (SWNT) bundles emit visible fluorescence in the presence of noble metal nanoparticles and nanorods in the solid state. Conductivity measurements with metallic nanotubes, isolated from pristine SWNTs, show that they become semiconducting in the presence of the metal nanoparticles. Nanoparticle binding increases the defects in the nanotube structures whi...

Increasing the hydrogen storage capacity of single-walled carbon nanotube (SWNT) through facile impregnation by TiO2, ZrO2 and ZnO nanocatalysts

Various nanocomposites of TiO2, ZnO and ZrO2 decorated single wall Carbon nanotubes (SWNTs) were fabricated by facile and template free continuous ultrasonication/stirring of virgin metal oxide nanopowders and SWNTs in ethanol under UV-light illumination. The TEM micrographs showed that nanoparticles (NPs) were uniformly dispersed and bonded on the surface of SWNTs. The results of XRD as well a...

pH dependence of water-solubility of single-walled carbon nanotubes treated by microplasma in aqueous solution

Single-walled carbon nanotubes (SWCNTs) were solubilized by microplasma in pH-controlled aqueous solution. The SWCNTs were highly dispersed and solubilized in water under higher pH condition (pH > 9). Surface of the SWCNT was functionalized by carboxylate ion (-COO) and negatively charged during the microplasma treatment. A possible mechanism of water-solubility of SWCNT was briefly discussed.
