Abstract
The present invention provides a method of collecting biomolecules via permeation through the skin of a subject, by energizing the stratum corneum in conjunction with various collection means including gels and dressing materials. Permeability enhancement or reduced electrical impedance of the skin increases the variety of substances capable of permeation, and increases the permeation rate and the effectiveness of the permeation, including permeation enhanced by iontophoresis. The method allows for the use of improved collection means that were previously unavailable.
