Journal ArticleDOI
Protein electrochemistry using aligned carbon nanotube arrays.
J. Justin Gooding,Rahmat Wibowo,Jingquan Liu,Wenrong Yang,Dusan Losic,Shannon Orbons,Freya J. Mearns,Joseph G. Shapter,D. Brynn Hibbert +8 more
TL;DR: In this paper, the authors showed that carbon nanotubes can be aligned normal to an electrode by self-assembly and act as molecular wires to allow electrical communication between the underlying electrode and redox proteins covalently attached to the ends of the SWNTs.
Journal ArticleDOI
Self-Assembled Monolayers into the 21st Century: Recent Advances and Applications
TL;DR: In this paper, a review of the use of self-assembled monolayers (SAMs) for modifying electrodes with an emphasis on the development of integrated molecular systems is presented.
Journal ArticleDOI
DNA Biosensor Concepts Based on a Change in the DNA Persistence Length upon Hybridization
Freya J. Mearns,Elicia L. S. Wong,Elicia L. S. Wong,Ken Short,D. Brynn Hibbert,J. Justin Gooding +5 more
TL;DR: Two types of biosensing concepts are explored, both based on the same basic switchable surface: a label-free system that uses air oxidation of the interface, followed by the change in accessibility of the surface upon hybridization to detect complementary target DNA, and a ferrocene-labeled system exploiting thechange in DNA flexibility alone.
Journal ArticleDOI
The ion gating effect: using a change in flexibility to allow label free electrochemical detection of DNA hybridisation
TL;DR: In this paper, a label free electrochemical method of detecting DNA hybridisation is presented based on the change in flexibility between a single strand of DNA and a duplex causing an ion-gating effect where hybridisation opens up the electrode to access of ions.
Journal ArticleDOI
Further development of an electrochemical DNA hybridization biosensor based on long-range electron transfer
TL;DR: An electrochemical DNA hybridization biosensor which exploits long-range electron transfer through double-stranded DNA (ds-DNA) to a redox intercalator is described in this paper.
