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...
متن کاملA novel fluorescent aptasensor based on single-walled carbon nanohorns.
Single-walled carbon nanohorns have been used to construct an aptasensor for the first time. This novel aptasensor was successfully used for the detection of thrombin with high sensitivity and excellent selectivity. This thrombin aptasensor has a detection limit of as low as 100 pM.
متن کاملLocalized modes in capped single-walled carbon nanotubes
It is well established that a special class of spatially localized modes can be generated at surfaces. Such surface states have been studied in many branches of physics, including electrons in crystals, surface phonons, surface polaritons, and optical surface modes in waveguide arrays. However, a direct observation of highly localized excitations at the atomic level is rather difficult. For exa...
متن کاملDNA-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.
متن کاملChemical Detection Using Single - Walled Carbon Nanotubes
We have developed electronic devices and sensors that use two-dimensional random networks of SWNTs as the active electronic material [1]. Such network devices display the aggregate properties of many randomly distributed SWNTs and can be processed into devices of arbitrary size using conventional microfabrication technology. We report here on the results of our efforts to develop chemical senso...
