Abstract
The present invention relates to a method of detecting (or identifying) particle(s) in a sample, particularly nanoparticles which, on entering the natural environment, may pose a public health risk. The method generally involves assessing the presence and/or properties of the particles in a sample from electrochemical responses yielded by the oxidative (or reductive) consumption/destruction of particles as they collide with a working electrode. In particular, the present invention allows identifying, quantifying, and characterising of particles in a sample via the electro-oxidation of particles which collide with working electrodes operating at a suitable potential difference.
