Electrode Comb Filters Nanoparticles from Blood Plasma

Electrode Comb Filters Nanoparticles from Blood Plasma
Nov-23-15
A new device able to filter nanoparticles from blood plasma for deeper study could have a significant impact on the evolution of the technology across a broad range of industries.

A team Jacobs School of Engineering created the filter specifically to allow researchers to remove nanoparticles from the blood plasma without altering their properties in any way. This ensures a more accurate study, and allows the researchers to determine how to improve the way the particles interact with the blood.

The filter removes the nanoparticles using an electric field generated by hundreds of tiny electrodes. The field creates a temporary charge imbalance between the particles and the fluid carrying them, which causes the nanoparticles to become attracted to the electrodes.
