Residual catalyst metal nanoparticles remain one of the major obstructions in the utilization of carbon nanotubes (CNTs) in many areas owing to their ability to participate in redox chemistry of biomarkers. Presented here is a comparative study of several techniques for quality control of carbon nanotubes in terms of metallic impurities, namely magnetic susceptibility, electron …
In this work, the synergy of one mature example from “lab-on-chip” domain, such as CE microchips with emerging miniaturized carbon nanotube detectors in analytical science, is presented. Two different carbon electrodes (glassy carbon electrode (GCE) 3 mm diameter, and screen-printed electrode (SPE) 0.3 mm x 2.5 mm) were modified with multiwalled carbon nanotubes (MWCNTs) and …
The electrochemical activation of multiwalled carbon nanotubes (MWCNTs) (at potentials of 1.5-2.0 V vs Ag/AgCl for 60-360 s) results in significantly increased rate constants (k(obs)(0)) for heterogeneous electron-transfer with [Fe(CN)(6)](3-14-) (from 8.34 x 10(-5)cms(-1) for as-received MWCNTs to 3.67 x 10(-3) cm s(-1) for MWCNTs that were electrochemically activated at 2.0 V for 180s). The …
The continuous upsurge in terrorist activity has generated tremendous demand for innovative tools capable of detecting nitrated organic, inorganic, and peroxide-based explosives. This article directly extends the previous exhaustive review (Electrophoresis 2006, 27, 244256) and overviews the research activity in the field of microchip and conventional capillary electrophoresis for analysis of a variety of explosive …
