Optimizing electroporation via pulse modulation: a molecular dynamics study.

Abstract

Efficient molecular transport via reversible electroporation requires sustained existence of the pore without causing irreversible cellular damage. In this study, we used molecular dynamics simulations to investigate pore formation during electroporation, and we characterized the transition to hydrophilic pores. Our simulations reveal that during the hydrophilic state, the reapplication of an electric field, even at reduced magnitudes, extends the pore duration while maintaining structural integrity. Furthermore, we established that the pore size can be controlled by regulating the intervals between successive electric field pulses, offering precise control over membrane permeabilization. These findings provide a foundation for fine-tuning electroporation protocols, enabling customized permeabilization strategies based on the properties of the molecules to be delivered. This approach has the potential to significantly improve the efficacy of targeted drug delivery and gene therapy. It also creates new possibilities for precise and controlled cellular manipulation in therapeutic contexts.
