Dispersion stability and exothermic properties of DNA-functionalized single-walled carbon nanotubes

Dispersion stability and exothermic properties of DNA-functionalized single-walled carbon nanotubes

Carbon nanotubes act as a photon antenna that serves as an effective "molecular heater" around the near-infrared (NIR) region. This exothermic generation can be used as a possible heating source for hyperthermia therapy. The current study reports the dispersible and exothermic properties with NIR irradiation for single-walled carbon nanotubes (SWNTs) treated with a strong acid (acid-treated SWN...

DNA-functionalized single-walled carbon nanotubes

We present here the use of amino-terminated DNA strands in functionalizing the open ends and defect sites of oxidatively prepared single-walled carbon nanotubes, an important first step in realizing a DNA-guided self-assembly process for carbon nanotubes.

Enzyme-mediated assimilation of DNA-functionalized single-walled carbon nanotubes.

When pyrimidine-functionalized carbon nanotubes were incubated with single-stranded DNA ligase, formations of macroscopic aggregates were observed. Wet-cell transmission electron microscopy imaging revealed that the nanotubes were radially bound to form a 3D latticelike structure. These structures were not observed in control reactions lacking ligase or adenosine triphosphate. Raman spectroscop...

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

DNA functionalized single-walled carbon nanotubes for electrochemical detection.

Single-walled carbon nanotubes (SWNTs) were effectively dispersed and functionalized by wrapping with single-stranded DNA (ssDNA). The ssDNA-SWNTs attach strongly on glass substrate and easily form a uniform film, making it possible for electrochemical analysis and sensing. The film was fabricated into a working electrode, which exhibited good electrochemical voltammetric properties, such as fl...
