Electrotaxis, also known as galvanotaxis, is the directed motion of biological cells or organisms guided by an electric field or current[1].
Overview
Biological cells can naturally sense and follow DC electric fields. Such electric fields arise naturally in biological tissues during development and healing.
History
In 1891, E. Dineur made the first known report of cells migrating directionally in a direct current, a phenomenon which he coined galvanotaxis[2]. Dineur used a zinc-copper cell to apply a constant current to the abdominal cavity of a frog and found that inflammatory leukocytes aggregated at the negative electrode. Since then, a variety of different cell types and organisms have been shown to respond to electric fields[3].
