Electrochemical characteristics of the immobilization of calf thymus DNA molecules on multi-walled carbon nanotubes

Electrochemistry of Eu(III) Binding to N-terminal of Euplotes Octocarinatus Centrin

“…The background current augment suggests an enlarged capacitive property in the presence of MWNTs. 26 The new peak is attributed to the Eu 3+ -N-EoCen/Eu 2+ -N-EoCen redox couples. It implies a new complex Eu 2 -N-EoCen is formed.…”

Carbon Nanotubes – Imprinted Polymers: Hybrid Materials for Analytical Applications

“…Microelectrodes are useful for measurements for changes in easily oxidized neurotransmitter concentrations in extracellular brain fluid (Kawagoe et al, 1993) The nanodimensions of CNTs guarantee a very large active surface area and are especially suited for the conception of miniaturized sensors. In addition to the high porosity and reactivity, this makes them ideal candidates for the storage of neutral species as well as electron donors, when used as electrodes in electrochemical reactions, for which they may also be called "nanoelectrodes" (Basabe-Desmonts et al, 2007;Daniel et al, 2007;Guo et al, 2004). Hence, it is not surprising that gas sensors made from individual nanotubes show good sensitivities at room temperature (J.…”

Carbon Nanotubes - A Potential Material for Affinity Biosensors

“…Also the principle based on DNA based biomolecular recognition has been applied to construct CNT-DNA electrochemical sensors [Daniel et al, 2007]. Guo et al, 2004 described the electrochemical characteristics of DNA functionalization of CNTs holds interesting prospects in various fields including solubilization in aqueous media, nucleic acid sensing, gene-therapy and controlled deposition on conducting or semiconducting substrates. DNA molecules can increase the CNT solubility and also be used to distinguish metallic CNT from semiconducting CNTs.…”

“…DNA is potentially a building block for the assembly of nanoscale electronic devices and has all the basic properties necessary for it with their application in decentralized clinical testing, food safety and environmental monitoring. The DNA nanoscale device construction will be a predominant technique of new molectron with attention paying benefits like high efficiency, low power requirement, miniaturization and low heat generation [Guo et al, 2004]. DNA immobilization considered as a fundamental methodology for construction of DNA biosensor, requires intimate connection between nucleic acid and electronic transducer.…”
