Under the optimized conditions, the relative fluorescence intensity decreased linearly with the copper ions concentration in the range from 2 to 200μg·L~(-1) and the detection limit could reach 0.29μg·L~(-1). Based on the charge-transfer quenching mechanism, the copper ions bounding onto the surface of qdots could absorb electrons from valance band, which results in the quenching of fluorescence.

用电荷转移机制解释了量子点荧光猝灭的原因，主要是由于价带电子激发到导带以后被表面结合的Cu~(2+)离子捕获而产生的结果，在此基础上，用光解实验进行了进一步的验证。

And 17 were capable of detecting specific metal ions by showing dramatic enhancement of fluorescence. In contrast with 15 and 17, the fluorescence signals of 13 and 14 were inefficiently altered by metal ions. Hence, 15 and 17 were further investigated with detailed 1H-NMR, UV-vis, and fluorescence titrations.

其中，15和17对特定金属离子有明显的侦测能力，混合后萤光强度会大幅增强，但13及14与金属离子混合后，萤光讯号的改变幅度不如15及17的显著，因此我们只对15和17进行详细的1H-NMR、UV-vis及萤光光谱的滴定。

Through this topic, we discover with the 2%NaOH-NALC digesting fluid may in 10 minute in rapid decomposition sputamentum resisting medium, during guarantee digestion effect not because the NaOH strong function will have killed the bacterium (timing control in 20 minutes), also will not affect the magnetic pellet the function; Through the application self-restraint quota simulation clinical specimen, we have compared the acid-fast stain and the pyoktanin yellow O fluorescence dye pick out limit, the pyoktanin yellow O fluorescence dyes the dark background to after-crop the obvious green bright the bacillus tuberculosis to compare in the acid-fast stain white background the red bacillus tuberculosis to accommodate strikingly, the pyoktanin yellow O fluorescence dyes picks out limits between 0.05~0.001 Mai unit, is higher than the acid-fast stain 0.05 Mai unit, the former sensitivity is high; Moreover, concentrates the function after magnetic nano particles the specimen smear, under the mirror demonstrated that its bacillus tuberculosis quantity is higher than the specimen which obviously has not passed through concentrates.
