Abstract
AbstractLow‐temperature plasma is a new transdermal drug delivery method that is different from the traditional physical and chemical methods. In this study, three touchable plasma jet devices are selected, such as direct current (DC) air plasma jet, DC helium plasma jet, and pulsed helium plasma jet. The patent blue V 1159.43 Da has been chosen for percutaneous penetration studies. The results show that 1 min DC air and helium plasma treatment significantly enhanced transdermal drug delivery by 9 and 26 times, respectively. The enhancement of pulsed plasma jet is the weakest. The skin histological analysis and reactive oxygen species (ROS) measurement shows that nonuniform distribution of ROS in DC helium and DC air plasma may cause perforation on the whole epidermis and allow more drug permeation.
