Mno2 Nanowires

Uniform encapsulated MnO2 nanowires were achieved within the cavity of multiwalled carbon nanotubes (MWCNTs). The Raman spectra revealed a charge-transfer shifts between the MnO2 particles and the inner tube of MWCNTs. Thin, uniform and continuous MnO2 was observed with a diameter of 9 nm.

DNA-nanosensor based on multiwalled carbon nanotubes (MWCNTs) decorated by nanocyclic thiophene-pyrrole complexes of octahedral high-spin Fe has been proposed for high-performance sensing of DNA-hybridization utilizing a surface-enhanced spin-dependent CNT-plasmon resonance. This DNA-nanosensor operates on screening and quenching effects at Raman scattering of light in duplexes DNA-probe/DNA-target at complementary pairing of nucleotides in DNA. Single nucleotide polymorphism (SNP) genotyping has been successfully performed for DNA samples from healthy and cancer-suffering donors.

Improved Raman interpretation of covalently functionalized MWCNTs arises from the distinction between spectral features related to aromaticity disruptions within the sidewalls and within the inner tubes.

Dispersions of individual carbon nanotubes (CNTs) are crucial for nanodevices and polymer/CNTs nanocomposites. In this paper, stable and homogenous dispersions of individual multiwalled carbon nanotubes (MWCNTs) have been synthesized. The factors influencing the dispersibility mechanism, including the surfactant concentration and the pH value, have been investigated. SEM images display the impurities sticking on MWCNTs which have been removed. The oxygen-containing groups on the surface of MWCNTs sample have been detected through FT-IR and Raman spectra. All experimental results illustrate that using fullerenols as surfactant can greatly improve the dispersibility of MWCNTs. Moreover, the prepared dispersions exhibit good stability that the sediment percentage of fullerenols-MWCNTs is only 5.2% after 5 days.
