Hybrid dielectrophoretic-optical trap for microparticles in aqueous suspension
Carlos D. Gonzalez-Gomez, Jose Garcia-Guirado, Romain Quidant +3
We demonstrate that a set of microfabricated electrodes can be coupled to a commercial optical tweezers device, implementing a hybrid electro-optical trap with multiple functionali…
3D Optofluidic Control Using Reconfigurable Thermal Barriers
Falko Schmidt, Carlos David Gonzalez-Gomez, Emilio Ruiz-Reina +3
Microfluidics has revolutionized control over small volumes through the use of physical barriers. However, the rigidity of these barriers limits flexibility in applications. We pre…
Electro-Thermo-Plasmonic Flow in Gold Nanoparticle Suspensions: Nonlinear Flow Velocity Dependence with Aggregates Concentration
Carlos David González Gómez, Raúl A. Rica, Emilio Ruiz-Reina
Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient l…
Non-Monotonic Concentration Dependence of the Electro-Phoretic Mobility of Charged Spheres in Realistic Salt Free Suspensions
Denis Botin, Felix Carrique, Emilio Ruiz-Reina +1
Using super-heterodyne Doppler velocimetry with multiple scattering correction, we extend the opti-cally accessible range of concentrations in experiments on colloidal electro-kine…
Ion size effects on the electrokinetics of salt-free concentrated suspensions in ac fields
Rafael Roa, Félix Carrique, Emilio Ruiz-Reina
We analyze the influence of finite ion size effects in the response of a salt-free concentrated suspension of spherical particles to an oscillating electric field. Salt-free suspen…
DC electrokinetics for spherical particles in salt-free concentrated suspensions including ion size effects
Rafael Roa, Félix Carrique, Emilio Ruiz-Reina
We study the electrophoretic mobility of spherical particles and the electrical conductivity in salt-free concentrated suspensions including finite ion size effects. An ideal salt-…
Ion size effects on the electric double layer of a spherical particle in a realistic salt-free concentrated suspension
Rafael Roa, Félix Carrique, Emilio Ruiz-Reina
A new modified Poisson-Boltzmann equation accounting for the finite size of the ions valid for realistic salt-free concentrated suspensions has been derived, extending the formalis…
Electric double layer for spherical particles in salt-free concentrated suspensions including ion size effects
R. Roa, F. Carrique, E. Ruiz-Reina
The equilibrium electric double layer (EDL) that surrounds the colloidal particles is determinant for the response of a suspension under a variety of static or alternating external…
