본 연구에서는, 동시에 넓은 면적을 조사할 수 있는 형태의 유전체 장벽 방전을 이용한 대기압 면방전 플라즈마 발생장치를 이용하여 곰팡이의 살균 실험을 수행하였다. 실험에 사용한 면방전 플라즈마 발생장치의 파워는 사인파 교류전원을 이용하였으며, 1.4∼2.3 kV의 방전전압을 가진다. 또한, 유전체 전기용량의 특성으로 인하여 전압과 전류의 위상차는 약 80도를 갖는다. 생물시료에 미치는 온도의 영향은 공랭식 쿨러를 사용하여 유전체의 열을 배출함으로써 최소화 하였으며, 시료의 온도는 온도측정장치를 사용하여 쿨러(Cooler) 작동 시 최대 10분간 플라즈마를 발생시켜도 37도가 넘지 않음을 확인하였다. 플라즈마에서 생성되는 활성종중 오존(O 3 )의 양은 플라즈마 발생부로부터 1 cm 이내에서 약 25∼30 ppm이 측정되었으며, 150 cm 떨어진 지점에서도 5 ppm 정도 측정되었다. 그에 비해 일산화질소(NO)나 이산화질소(NO 2… 
Evaluation of the Sterilization Effect of a Plasma Generator with a Flexible Electrode Structure on Staphylococcus aureus and Pseudomonas aeruginosa
본 연구에서 유연전극 구조의 플라즈마 발생기를 이용하여 S. aureus 와 P. aeruginosa의 살균 능력을 평가하였다. 두 균주 모두 1.5×106 CFU/mL 농도의 부유액으로 조제하여 배지에 도말 후, 플라즈마 발생기로부터 3 cm, 9 cm 떨어뜨려 15초 간격으로, 30초부터 120초까지 그리고 3분, 5분, 10분 동안 플라즈마를

Temperature dependence of protein folding kinetics in living cells
TLDR
It is shown that the protein is stabilized by about 6 kJ/mole in the cytoplasm, but the temperature dependence of folding kinetics is similar to in vitro, which can be rationalized in terms of temperature-dependent crowding, local viscosity, or hydrophobicity.
