Abstract
This paper describes a microfluidic device, fabricated in poly(dimethylsiloxane), that is used for potentiometric titrations. This system generates step gradients of redox potentials in a series of microchannels. These potentials are probed by microelectrodes that are integrated into the chip; the measured potentials were used to produce a titration curve from which the end point of a reaction was measured.Keywords
