Abstract

Both field-confined skin electroporation and microscissioning offer minimally invasive methods for delivering drugs across skin and nail with minimal sensation. Both methods create high permeability pathways in a pain-free manner. These openings are similar in dimension to commonly experienced scratches and nicks on the skin. These localized openings provide pathways for sustained delivery of drugs either passively using a patch or actively using pressure or iontophoresis.
