Before revision:  This current is demonstrated to  add directly to the longitudinal current  resulting from an external voltage source, and could be significant in amplifying low-intensity endogenous currents within the cellular environment  .
After revision:  This current is demonstrated to add directly to the longitudinal current resulting from an external voltage source, and could be significant in amplifying low-intensity endogenous currents within the cellular environment or as a nano-bioelectronic device .
