Abstract
The erythrocyte ghosts were irradiated with doses of 100 to 1000 Gy. The fluorescence intensity and the lifetime of the excited state of pyrene and diphenylhexatriene were shown to decrease. The analysis of the results obtained has demonstrated that the changes in the fluorescence parameters of these probes are related to the enhanced dynamic probe quenching, the quencher being placed in water or the water itself being a quencher.
摘要
将红细胞血影用100至1000戈瑞的剂量进行辐照。结果表明，芘和二苯基己三烯的荧光强度以及激发态寿命均降低。对所得结果的分析表明，这些探针荧光参数的变化与动态探针猝灭增强有关，猝灭剂置于水中或水本身就是猝灭剂。
