WebThe selected gel formula was applied using the Phoresor Unit II iontophoresis device with TransQe iontophoresis electrodes of an active area of 13.4 cm 2 for 30 minutes (IOMED, Inc., Salt Lake City, UT, USA), the current density was adjusted to be 0.2mA/cm 2, 22,26,27 A 0.5 mL blood sample was collected from the retro-orbital vein and put into heparinized … WebThe iontophoresis delivery of insulin (INS) remains a serious challenge due to the low permeability of the drug through the skin. This work aims to investigate the potential of water-soluble polypyrrole nanoparticles (WS-PPyNPs) as a drug donor matrix for controlled transdermal iontophoresis of INS. WS-PPyNPs have been prepared via a simple …
