Recent research into cold atmospheric plasma suggests its potential in medical applications, particularly for improving drug delivery through skin by evaluating different dielectric barrier discharges (DBDs).
Various imaging techniques and electrical resistance measurements were utilized to assess how effectively different types of DBDs could create pores in the outer layer of human skin (stratum corneum).
The study found that μs-pulsed DBDs were effective at forming pores, while ns-pulsed DBDs were gentler and less damaging, emphasizing the need for tailored plasma characteristics for specific treatment purposes.
