Staggered independent microneedle arrays apply electroporation in skin to improve nucleic acid vaccine cell uptake and immune response.
A guided microneedle array improves stable insertion and uniform solution delivery to skin and subcutaneous fat with fewer procedures.
A rotating gate and magnetic reservoir keep the drug sealed during movement, then open at the target for accurate contamination-free release.
Surface channels guide liquid into mold depressions and even out drying, reducing cavities, brittleness, and scrap in microneedle array production.
