Charging of Heated Colloidal Particles Using the Electrolyte Seebeck Effect
Charging of Heated Colloidal Particles Using the Electrolyte Seebeck Effect
We propose a novel actuation mechanism for colloids, which is based on the Seebeck effect of the electrolyte solution: Laser heating of a nonionic particle accumulates in its vicinity a net charge $Q$, which is proportional to the excess temperature at the particle surface. The corresponding long-range thermoelectric field $E\ensuremath{\propto}1/{r}^{2}$ …
