本文报道了利用真实的时间原位电子自旋共振（ESR）技术对原子氧等离子体放电作用下真菌指状青霉（Penicilliumdigitatum）孢子表面自由基的动力学分析。我们已经获得的信息，从孢子的ESR信号被观察到，并初步分配到半醌自由基的g值约为2.004和线宽约为5G。信号的衰减可能与真菌孢子的失活有关。实时原位ESR已被证明是一种有用的方法来阐明等离子体诱导的生物样品的表面反应。
We report the kinetic analysis of free radicals on fungal spores of Penicillium digitatum interacted with atomic oxygen generated plasma electric discharge using real time in situ electron spin resonance (ESR) measurements. We have obtained information that the ESR signal from the spores was observed and preliminarily assignable to semiquinone radical with a g-value of around 2.004 and a line width of approximately 5G. The decay of the signal is possibly linked to the inactivation of the fungal spore. The real-time in situ ESR has proven to be a useful method to elucidate plasma-induced surface reactions on biological specimens.
