TL;DR: The cyclic voltammetric and kinetic data presented can serve as a benchmark for research groups evaluating the electrochemical properties of semimetallic (i.e., conductive), hydrogen-terminated, polycrystalline diamond.
Journal ArticleDOI
High-throughput selection, enumeration, electrokinetic manipulation, and molecular profiling of low-abundance circulating tumor cells using a microfluidic system.
Udara Dharmasiri,Samuel K. Njoroge,Małgorzata A. Witek,Morayo G. Adebiyi,Joyce W. Kamande,Mateusz L. Hupert,Francis Barany,Steven A. Soper +7 more
TL;DR: A circulating tumor cell (CTC) selection microfluidic device was integrated to an electrokinetic enrichment device for preconcentrating CTCs directly from whole blood to allow for the detection of mutations contained within the genomic DNA of the C TCs.
Journal ArticleDOI
Characterization and Electrochemical Responsiveness of Boron-Doped Nanocrystalline Diamond Thin-Film Electrodes
TL;DR: The nanocrystallinity is a result of a growth and nucleation mechanism discovered by Gruen, which involves the insertion of C2 carbon dimer into C−H bonds on the growth surface as mentioned in this paper.
Journal ArticleDOI
Materials and microfluidics: enabling the efficient isolation and analysis of circulating tumour cells.
Joshua M. Jackson,Małgorzata A. Witek,Małgorzata A. Witek,Joyce W. Kamande,Steve Allan Soper +4 more
TL;DR: A critical review of microfluidic technologies and material effects on the analyses of circulating tumour cells (CTCs) selected from the peripheral blood of cancer patients and context to how CTC isolation technologies enable downstream analysis of selected CTCs is given.
Journal ArticleDOI
Electrochemical oxidation of polyamines at diamond thin-film electrodes
TL;DR: In this article, the oxidation of five polyamines (ethylenediamine, putrescine, cadaverine, spermine, and spermidine) was investigated at polycrystalline, boron-doped, diamond thin-film electrodes using cyclic voltammetry and flow injection analysis (FIA) with amperometric detection.
