Breathable, Stretchable Electroporation Patches for Drug Delivery

Area of Science:

• Biomedical Engineering
• Materials Science
• Dermatology

Background:

• Arthritis is a growing global health concern, particularly in aging populations.
• Transdermal drug delivery offers advantages like high bioavailability but faces challenges including cost, comfort, and tissue damage.
• Existing wearable drug delivery systems often have limitations in practicality and patient comfort.

Purpose of the Study:

• To develop a low-cost, breathable, and stretchable electroporation patch (BSEP) for enhanced transdermal drug delivery.
• To integrate traditional drug patch technology with electroporation for improved drug penetration.
• To assess the safety, biocompatibility, and efficacy of the novel BSEP device.

Main Methods:

• Screen printing conductive ink onto a breathable, stretchable non-woven fabric substrate.
• Utilizing a serpentine interdigitated electrode design to localize electric fields in superficial skin layers.
• Conducting cytotoxicity tests, histological analyses, and animal experiments to evaluate device performance and safety.

Main Results:

• The BSEP demonstrated biocompatibility and safety through cytotoxicity and histological assessments.
• The unique electrode design reduced voltage in deep tissues by over 50%, minimizing potential damage.
• Animal studies showed a two-to-threefold increase in skin drug penetration compared to controls, validating BSEP's efficacy.

Conclusions:

• The developed breathable, stretchable electroporation patch (BSEP) offers a promising, low-cost solution for enhanced transdermal drug delivery.
• BSEP technology effectively increases drug penetration while ensuring safety and minimizing tissue damage.
• This innovation holds significant potential for improving arthritis treatment and other transdermal therapeutic applications.
