Cupric chloride dihydrate (CuCl2·2H2O, 99%), tetrachloroaurate trihydrate (HAuCl4·3H2O, 99%) and glucose (α or β form) were purchased from Sinopharm Chemical Reagent Co. Ltd (Shanghai, China). HDA (90%) was obtained from Sigma-Aldrich. All the vials were made from borosilicate glass, with a black phenolic-moulded screw cap and polyvinyl-faced pulp liner. Ultrapure Millipore water (18.2 MΩ) was used as the solvent throughout.

Synthesis of CCNTs and N-GQDs

Check if the same lab product or an alternative is used in the 5 most similar protocols
CV was purchased from Shanghai Yuanye Bio-Technology Co., Ltd., cupric chloride dihydrate, citric acid monohydrate, and potassium persulfate were obtained from Sinopharm Chemical Reagent Co., Ltd., China. Phosphate-buffered saline (PBS) solutions with various pH values were prepared by stock solution of 0.1 mol/L KH2PO4 and K2HPO4. All other chemicals were of analytical grade and used without further purification. The solutions were prepared by using doubly distilled water.
The CCNTs were prepared as follows: 0.2 g CNTs were added into 100 mL 3:1 (v/v) H2SO4:HNO3, then refluxed at 120°C for 1 h, the solution was finally filtered using a 0.8-μm membrane. The residue was washed by water until pH = 7 and dried in an oven at 60°C for 8 h to obtain the CCNTs.
The N-GQDs were prepared as followes: 8.0 g citric acid monohydrate and 1.0 mL ammonia were added into an autoclave and heated at 210°C for 1.5 h, and then cooled to room temperature naturally. After cooling to room temperature, the N-GQDs solution was mixed with excess ethanol, allowed to stay there for 15 min, and then centrifuged at 13000 rpm for 5 min to remove any impurities. After purification, the resultant N-GQDs was diluted to 50 mL with water for further use.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
