A team of researchers from National Cheng Kung University (NCKU) in Tainan City, Taiwan, have designed a portable micro-plasma device (PMPD) that could be used to repair the skin after laser surgery. The research team is led by Dr Jiunn-Der Liao, Professor of Department of Materials Science and Engineering at NCKU.
The PMPD is a mild treatment with a temperature that can be adjusted to body temperature to induce growth factor and reduce the healing time after laser surgery. The ultimate goal of skin repair after laser surgery is to achieve better effects by minimising damage and reducing complications. Liao believes that, for this purpose alone, PMPD performs well in treating the living skin without causing damage.
The current application of plasma technology in skin care is limited to the heat generated by the plasma to replace the laser while the advantage of the PMPD is that it lowers the plasma temperature to room temperature to treat the sensitive skin in a milder way. The researchers say the key feature of the PMPD is that it can accelerate wound healing and significantly shorten the healing time after laser surgery by using the micro-plasma to stimulate cell proliferation and skin regeneration. It could also achieves the most positive impact while conserving energy by dividing the supply of the gas.
The PMPD intellectual property is protected by patents in Taiwan, Japan, the US and China, and is scheduled to complete clinic trials on humans in 2013 and enter the market in 2014. NCKU, under the sponsorship from National Science Council (NSC), will help the team carry out technology transfer in the hope that the novel treatment will be available to people who need skin repair.
