biofilm infection
It is known that electric current inhibits bacterial growth. However, the current modalities of administering electric field technology as a therapy require a battery or an external power source. Thus, there has not been a practical way to administer electric current to mitigate biofilm infection in wound care. This study introduces a novel electroceutical dressing consisting of a silver–zinc electrocouple to generate a low electric field (∼1 V). The dressing becomes activated by a moist environment, inducing transient and micromolar amounts of superoxide anion radicals inhibiting bacterial growth.
