Charged droplet transportation under direct current electric fields as a cell carrier

摘要

This study verifies the reliability of the cell transport through charged droplets under DC electrical fields. Over 90% cell viability can be obtained after charging and discharging for thousands of times. The high cell viability indicates that the electrical charging of a droplet barely influences the cells inside over a long working period. DC field induced AC electrical signals via droplet motion are also observed and analyzed quantitatively. The measured AC signals help us understand the charge transfer of a droplet during charging and discharging processes.
