Femtomolar detection of silver nanoparticles by flow-enhanced direct-impact voltammetry at a microelectrode array by Stanislav V. Sokolov, Thomas R. Bartlett, Peter Fair, Stephen Fletcher, Richard G. Compton

“…The resulting limit of detection is more than 2 orders of magnitude smaller than the previous detection limit for direct-impact voltammetry (900 fM) [J. Ellison et al. Sens. Actuators, B 2014, 200, 47], and is more than 30 times smaller than the previous detection limit for mediated-impact voltammetry (83 fM) [T. …”
