[求助] 量子點(diǎn)的制備

這是文獻(xiàn)中量子點(diǎn)的制備部分，求大神翻譯精確，畢竟是操作步驟，一字錯(cuò)也有可能整個(gè)實(shí)驗(yàn)出錯(cuò)。還希望翻譯者告示1和2是步驟的承接（就是做完1再做2），還是2是獨(dú)立的步驟（就是1是1，2是2，都是獨(dú)立的步驟）？？

1，Synthesis of CDs and AuNCs.
The CDs were synthesized by microwave-assisted method. Freshly prepared aqueous solution of glucose was heated in a domestic microwave for 20 min. The obtained product was centrifuged and then the resultant supernate containing luminescent CDs was dialyzed with a dialysis tube (molecular weight 1000) against doubly distilled water for 24 h, and finally, the product was obtained. Meanwhile, fluorescent gold nanoclusters (AuNCs) were prepared by HAuCl4 and glutathione (GSH) using microwaveassisted method for 20 min.
2，Synthesis of GCDs.
The GCDs were synthesized based on the modification of preparing CDs and AuNCs. Typically, 5 mL of 20 mM freshly prepared HAuCl4 aqueous solution and 1.5 mL of 100 mM GSH were mixed, and then the mixture solution was diluted by distilled water up to 50 mL in a round bottomed flask at room temperature. The mixture was heated to 80 °C under gentle stirring for 2 h. Then the mixture was transferred into a conical flask and dissolved 2 g glucose. The resulting solution was heated in a domestic
microwave for 20 min. The obtained product was dissolved again and centrifuged (16 000g, 30 min). After that, the resultant supernatant containing luminescent GCDs were dialyzed with a dialysis tube (molecular weight 8000−14 000) against doubly distilled water for 24 h, and finally the product was obtained.

1，CD和AuNC的合成。
通過微波輔助方法合成CD。新配制的葡萄糖水溶液于家用微波爐中加熱20分鐘得到的產(chǎn)物甩干，然后用雙倍蒸餾水通過一種滲析管(分子量1000)對所形成的含有發(fā)光的CD的上層液進(jìn)行滲析24小時(shí),最后得到產(chǎn)物。ined. 同時(shí)采用微波輔助方法由HAuCl4和谷胱甘肽(GSH)制備熒光金納米簇(AuNC) 20分鐘。
2，GCD的合成。
在CD和AuNC制備方法改進(jìn)的基礎(chǔ)上合成GCD。通常情況在室溫下于一個(gè)圓底的燒瓶中先將5毫升20mM的新配制的HAuCl4水溶液和1.5毫升100mM的GSH混合,然后用蒸餾水稀釋混合物溶液至50毫升。溫和攪拌下混合物加熱至至80°C２小時(shí)。然后將混合物移至一個(gè)錐形燒瓶溶解2克葡萄糖。得到的溶液于家用微波爐中加熱20分鐘。所得產(chǎn)物再次溶解并甩干(16000g, 30分鐘）。然后，用雙倍蒸餾水通過一種滲析管(分子量8000?14 000)對所形成的含有發(fā)光CD的上層液進(jìn)行滲析24小時(shí),最后得到產(chǎn)物。
