DNA translocating through a carbon nanotube can increase ionic current

The effect of translocating cylindrical particles on the ionic current through a nanopore.

The electric field-induced translocation of cylindrical particles through nanopores with circular cross sections is studied theoretically. The coupled Nernst-Planck equations (multi-ion model, MIM) for the concentration fields of the ions in solution and the Stokes equation for the flow field are solved simultaneously. The predictions of the multi-ion model are compared with the predictions of ...

Direct DNA Immobilization onto a Carbon Nanotube Modified Electrode: Study on the Influence of pH and Ionic Strength

Over the past years, DNA biosensors have been developed to analyze DNA interaction and damage that have important applications in biotechnological researches. The immobilization of DNA onto a substrate is one key step for construction of DNA electrochemical biosensors. In this report, a direct approach has been described for immobilization of single strand DNA onto carboxylic acid-functionalize...

One hundred fold increase in current carrying capacity in a carbon nanotube–copper composite

Increased portability, versatility and ubiquity of electronics devices are a result of their progressive miniaturization, requiring current flow through narrow channels. Present-day devices operate close to the maximum current-carrying-capacity (that is, ampacity) of conductors (such as copper and gold), leading to decreased lifetime and performance, creating demand for new conductors with high...

Conductance Through a Bent Carbon Nanotube

In this thesis a theoretical expression for the conductance through a bent nanotube is derived. The idea is inspired by a recent work by K. Flensberg and C. Markus, in which bent nanotubes are shown to be a prominent candidate for qubit realization [1]. An approximate Hamiltonian for graphene in the vicinity of the high-symmetry K(K′)-points is developed from the tightbinding model. An extensio...
