FIG. 6.
Key parameter optimizations for the core-shell spherical DEP polarization model for ELP-PEI treated hMSCs at 0.10 S/m. (a) Decreases from literature values in membrane permittivity better capture ELP-PEI treated hMSCs nDEP behaviors. (b) Increases or decreases in membrane conductivity do not contribute to the experimentally observed nDEP. (c) Decreases in cytoplasm permittivity also do not contribute. (d) Decreases in cytoplasm conductivity may contribute to the nDEP behavior with σcyto = 6.3 × 10−3 S/m fitting well. (e) Model prediction for both untreated and treated hMSCs at 0.10 S/m using all optimal parameters for each. Agreement between the model and the data is quite good with an overall 2.5% error.
