Combining electrokinetics with impedance spectroscopy for bacterial detection

What is it about?

Planar biosensors suffer from the low capture/deposition rate of biospecies on their surface. To solve this, we use electrokinetic effects to attract bacterial cells directly on the sensor surface and demonstrate a significantly higher sensitivity.

Why is it important?

We propose a) a unique electrode design to combine impedance spectroscopy with electrokinetics, b) the use of resonance to enhance electrokinetics, c) the combination of short- and long-range electrokinetics effect to efficiently trap bacteria.
