Electroporation

Definition

Electroporation is a technique that uses short bursts of high voltage to create temporary pores in cell membranes, allowing substances like drugs or DNA to enter the cells more easily. This method has gained attention for its potential in enhancing drug delivery and gene therapy, particularly in wearable drug delivery systems where non-invasive techniques are essential. By leveraging electroporation, therapeutic agents can be delivered effectively through the skin without the need for needles, making it a promising approach in modern medicine.
