Characterization and optimization of liquid electrodes for lateral dielectrophoresis

Philippe Renaud, Harald Van Lintel, Nicolas Demierre, Urban Seger, Olof Pontus Linderholm, Thomas Michael Braschler

Using the concept of insulator-based "electrodeless" dielectrophoresis, we present a novel geometry for shaping electric fields to achieve lateral deviation of particles in liquid flows. The field is generated by lateral planar metal electrodes and is guid ...

Effect of the surface charge on ion transport through nanoslits

Philippe Renaud, Harald Van Lintel, Reto Bruno Schoch

A description of ion transport through geometrically defined nanoslits is presented. It is characterized by the effective surface charge density and was obtained by impedance spectroscopy measurements of electrolytes with different physico-chemical propert ...

The rod and hole paradox re-examined

Christian Gruber, Harald Van Lintel

In the rod and hole paradox as described by Rindler (1961 Am. J. Phys. 29 365–6) ('length contraction paradox'), a rigid rod moves at high speed over a table towards a hole of the same size. A bystander expects the rod to fall into the hole, but a co-movin ...

Study of micro-glow discharges as ion sources for ion mobility spectrometry

Philippe Renaud, Harald Van Lintel

We develop a microionizer as the ion source in a miniaturized spectrometerlike gas analyzer, operating at atmospheric pressure. Several options for the ionizing principle were considered. The application of dc glow discharge in a microsystem was studied in ...

A high-performance silicon micropump for disposable drug delivery systems

Philippe Renaud, Harald Van Lintel

This paper describes the design, fabrication and experimental results of a new, low cost, high-performance silicon micropump developed for a disposable drug delivery system. The pump chip demonstrates linear and accurate (+/-5%) pumping characteristics for ...

Study of gas ionization schemes for micro devices

Christoph Hollenstein, Philippe Renaud, Harald Van Lintel

For the development of micro gas sensors, studies of field ionization and break-down in small gaps were performed. A finite element simulation was done for an estimate of the achievable field strength near a nanotube tip in small gaps. The simulation also ...
