AFM imaging of functionalized double-walled carbon nanotubes.

AFM imaging of functionalized carbon nanotubes on biological membranes.

Multifunctional carbon nanotubes are promising for biomedical applications as their nano-size, together with their physical stability, gives access into the cell and various cellular compartments including the nucleus. However, the direct and label-free detection of carbon nanotube uptake into cells is a challenging task. The atomic force microscope (AFM) is capable of resolving details of cell...

Structural and functional imaging with carbon nanotube AFM probes.

Atomic force microscopy (AFM) has great potential as a tool for structural biology, a field in which there is increasing demand to characterize larger and more complex biomolecular systems. However, the poorly characterized silicon and silicon nitride probe tips currently employed in AFM limit its biological applications. Carbon nanotubes represent ideal AFM tip materials due to their small dia...

Binding of rigid dendritic ruthenium complexes to carbon nanotubes.

Single-walled carbon nanotubes (SWNTs) bind strongly to rigid ruthenium metallodendrimers. High valence ions effectively coagulate these nanotubes from stable dispersions in N,N-dimethylforamide. While ruthenium salts and small [Ru(diimine)(3)](2+) complexes also coagulate the nanotubes, they require much higher concentrations and are easily extracted from the nanotubes with acetonitrile. Enant...

Vibroelectronic Properties of Functionalized Single- Walled Carbon Nanotubes and Double-walled Boron Nitride Nanotubes

Linkage of doxycycline onto functionalized multi-walled carbon nanotube and morphological characterization

In this paper functionalized multiwall carbon nanotubes (FMWCNT) were modified using doxycycline, containing reactable nitrogen, which can attach chemically to functionalized MWCNT. The synthesized nano compounds were characterized by Fourier transform infrared spectroscopy (FT-IR) and Raman spectroscopy. These spectrums proved the existence of nitrogen atoms of amide functional groups. The mor...
