Microneedling have shown to start collagen formation and production of healing agents but without removing epidermis and without causing hyperpigmentation.8 Hence
microneedle therapy promotes healing with less epidermal damage and small recovery time than other ablative or resurfacing techniques.9
"This is maybe 5 or 10 years off in the future, but this method could be painless upon delivery of antigen on either coated solid
microneedles or within dissolving
microneedles only to the epidermis, which lacks nerve endings," Dr.
With our new dry powder and
microneedle technologies, 3M can fulfill DPI and MDI inhalation needs as well as both passive and active transdermal manufacturing.
Engineers Mark Prausnitz and Mark Allen at the Georgia Institute of Technology have developed a skin patch of
microneedles (needles thinner and shorter than the diameter of a human hair), which they hope will eventually deliver painless medication.
Researchers at CUMC and the University of North Carolina have designed a
microneedle skin patch that delivers fat-shrinking drugs locally.
The closed balloon provides a protective covering for a tiny, perpendicular-oriented injection
microneedle as it is guided safely through the vascular system to target vessels with diameters of 2 to 8 millimetres.
Specific transdermal and intradermal drug delivery techniques are then described, including techniques such as cryo-TEM, microcorporation,
microneedle technology, film-forming and heated systems, nanotechnology-based applications, and magnetophoresis.
