The multi-walled carbon nanotubes (MWCNTs)-polyamidoamine (PAMAM) hybrid was prepared by covalent linkage approach, and characterized by transmission electron microscopy, Fourier transform infrared spectroscopy and ultraviolet-visible spectrometry. The PAMAM dendrimers were present on the surface of MWCNTs in high density, and the MWCNT-PAMAM hybrid(More)
Three types of functionalized carbon nanotubes (f-CNTs), polyamidoamine (PAMAM) dendrimer-functionalized single and multi-walled CNTs (MWCNT-PAMAM-1, MWCNT-PAMAM-2, and SWCNT-PAMAM-3), were prepared by covalent linkage approach. The micro-morphologies of the three f-CNTs and the interaction of MWCNT-PAMAM-2 with HeLa cells were characterized by transmission(More)
CdSe/ZnS core-shell quantum dots (QDs) were efficiently tethered onto polyamidoamine dendrimer-modified multi-walled carbon nanotubes (MWCNTs) by covalent linkage and mercapto-mediated assembly. The obtained MWCNT-QD hybrids were both photophysically and morphologically characterized. The QDs are well-distributed on single nanotube surface in high density(More)
