[求助] 求大神幫忙翻譯一個(gè)摘要，急急急!!!!!!!!

在前期研究的基礎(chǔ)上，采用水合肼還原二氧化硒一步合成粒度分布均勻且熒光量子產(chǎn)率高的水溶性CdSe 量子點(diǎn)。在此基礎(chǔ)上，以合成的CdSe 量子點(diǎn)為熒光物構(gòu)建量子點(diǎn)“開關(guān)”。由于茜素紅能使量子點(diǎn)的熒光有效猝滅及茜素紅能接受氨基氮原子上的孤對(duì)電子形成n-п絡(luò)合物，因此，在CdSe量子點(diǎn)-茜素紅熒光猝滅體系中加入含氨基的阿米卡星，量子點(diǎn)的熒光得以恢復(fù)，據(jù)此建立一種熒光恢復(fù)測定阿米卡星含量的新方法；雙硫腙結(jié)合到量子點(diǎn)表面后通過熒光共振能量轉(zhuǎn)移使量子點(diǎn)熒光猝滅，汞離子與雙硫腙分子之間又存在強(qiáng)烈的配位作用，因此，在雙硫腙修飾的CdSe量子點(diǎn)溶液中加入汞離子后，雙硫腙分子因與汞離子的配位作用而脫離量子點(diǎn)表面，結(jié)果量子點(diǎn)的熒光得以恢復(fù)，據(jù)此建立一種熒光恢復(fù)測汞的新方法。本課題的研究對(duì)拓展CdSe量子點(diǎn)的應(yīng)用具有重要意義，也為阿米卡星和汞離子的測定提供一種新方法。

Based on previous studies, a water-soluble CdSe quantum dots with narrow particle size distribution and high fluorescence quantum yield were synthesized by a one-step reduction method from selenium oxide and hydrazine hydrate. On the basis of this result, the quantum dots of CdSs were synthesized and used as the fluorescence source to construct a quantum dot-base molecular switch. The alizarin red can effectively quench the fluorescence of quantum dots, and the fact that alizarin red can accept the lone pair electrons on the amino nitrogen to form a n- pai coordination complex, therefore, adding an amino-containing Amikacin to the CdSe quantum dot-alizarin red fluorescence quenching system can restore the fluorescence from quantum dots. Based this we establishes a new fluorescence recovery method for the quantitative measurement of Amikacin; Dithizone binds to the surface of quantum dots, it can also cause quenching of fluorescence from quantum dots through fluorescence resonance energy transfer. There is a strong coordination between mercury ion and dithizone, and therefore, with the addition of mercury ions to dithizone-modified CdSe quantum dots, the dithizone was stripped from the surface of quantum dots, which resulted in the restoration of the fluorescence from quantum dots. Based this, another new fluorescence recovery method for the measurement of Hg2+ was established. The research of this thesis provided a significant advancement for the application of CdSe quantum dots, and it also provides new methods for the determination of Amikacin and mercury ion.
