Therefore, the sandwich epidermis model was used in case of magnetophoresis mediated studies to elucidate the mechanism of appendageal pathway. Menu Formats. Conclusions The enhancement factor due to combination of chemical permeation enhancer was additive and not synergistic. Previous studies by Murthy et al. Electroporation: In electroporation, short electric pulse milliseconds or microseconds is applied to the skin for the transitory structural perturbation of the lipid bilayer membranes. Therefore to add supportive evidence to the magnetohydrokinesis phenomenon, transport of 14 C-mannitol across the epidermis was investigated. Protein Structures. Local and transient structural changes in stratum corneum at high electric fields: contribution of Joule heating.
