短波長微生物光抑制技術分析與應用

Analysis and Application of Short-wavelength Light Inhibition Technology for Virus and Bacteria

2019年底由嚴重急性呼吸系統症候群冠狀病毒引發的特殊傳染性肺炎，於2020年初於全球迅速擴散，台灣醫療在歷經2002年SARS及2009年A型流感病毒H1N1疫情後，在政府扶植及民間投資下，針對此次新冠病毒（COVID-19）積極開發各項防疫技術，除了減少飛沫傳染的口罩外，消毒技術亦為發展重點，其中以光抑制方式破壞病毒結構則屬最方便且可被廣泛應用之方式。本研究開發短波長光抑制系統，並實際於第二等級生物實驗室進行病毒驗證生物測試與分析。實驗結果得知以50mJ/cm^2以上之光劑量照射時，對病毒有99.99%之抑制率。
At the end of 2019, the special infectious pneumonia caused by severe acute respiratory syndrome coronavirus that spread rapidly around the world in early 2020. After the 2002 SARS and 2009 influenza A virus H1N1 outbreaks in Taiwan, Taiwan's medical treatment was supported by government support and private investment. For the new coronavirus (COVID-19), actively develop various anti-epidemic technologies in Taiwan. Therein, the masks is a necessary object which can reduce the infection of droplets, and the disinfection technology is also the focus of development. Among them, the use of light suppression to destroy the virus structure is the most convenient and can be widely used and applied in our life. This research develops a short-wavelength light suppression system and actually conducts a biological testing for virus verification in Biosafety level 2 environment (P2 Lab). The experiments show that when the virus of 229E was irradiated with a light dose of 50 mJ/cm2 or more, the virus has a 99.99% inhibition rate.
