Electrokinetic Library of Microorganisms

Microscale BioSeparations Laboratory

 

eEEEC= empirical Electrokinetic Equilibrium Condition, which is to be used as an EK signature for each type of microorganism for the design of insulator-based separation systems.

·         For more information on how to use the eEEEC please refer to this article [1].

·         Publication on the derivation of the parameter EEEC [2]

·         Publication on bacterial and yeast cells [3].

·         Publication on bacteriophage virus [4].
