Direct electrochemistry of copper oxide nanoparticles in alkaline media
- Wei Zhe Teo, Adriano Ambrosi, Martin Pumera*
The use of metallic nanoparticles in consumer products is growing, posing health threatening issues as they are being released into the environment As such, there is an urgent need for a facile method to be used for the detection and quantification of metallic nanoparticles present in a sample. In this work, the electrochemical behavior of copper oxide nanoparticles in alkaline media has been exploited to develop a sensitive electrochemical method for their determination achieving a quantification limit of 50 ng. This technique may be also applied for quantification of other metallic nanoparticles in the future. (C) 2012 Elsevier B.V. All rights reserved.
