Titanate nanosheet material was synthesized as describe previously by Sasaki [24 ] and by Harito et al. [20 ]. Anthraquinone (molecular weight 208.21 g mol−1; CAS: 84-65-1; 97%), 1-amino-Anthraquinone (molecular weight 223.23 g mol−1; CAS: 82-45-1; 97%), decamethylferrocene (molecular weight 326.30 g mol−1; CAS: 12126-50-0; 97%), 5,10,15,20-tetraphenyl-21H,23H-porphine manganese (III) chloride (TPPMnCl; molecular weight 703.11 g mol−1; CAS: 32195-55-4; 95%), and ±α-tocopherol (molecular weight 430.71 g mol−1; CAS: 10191-41-0; ≥96%) were obtained from Sigma-Aldrich. Sodium dihydrogen phosphate and sodium phosphate dibasic hexa-hydrate (for buffer preparation), sodium chloride, cyclopentanone, acetone, chloroform, dichloromethane, and ethanol were purchased from Sigma-Aldrich, Fisher Scientific, or VWR BDH Chemicals and used without further purification. Solutions were prepared under ambient condition in volumetric flasks with ultrapure water with resistivity of 18.2 MOhm cm (at 22 °C, from an ELGA Purelab Classic system).

Example 1
1-aminoanthraquinone (46.0 parts) commercial available such as from Sigma Aldrich, is dissolved in concentrated sulfuric acid (98%, 200 mL) at 60° C. When the product is completely dissolved, the temperature is decreased to room temperature before slow addition of ice (800.0 parts) with efficient stirring. To the resulting slurry at 0-5° C. is then added drop wise bromine (72.4 parts) over a period of 3 hours. The resulting mixture is stirred at room temperature for 20 hours. Excess bromine is then removed by bubbling nitrogen in the reaction mixture. The precipitate is then filtered and washed with water (1000 mL). The wet press-cake is stirred in 8 wt % aqueous sodium hydroxide solution (1000 mL) for one hour, filtered, successively washed with water (1000 mL), 20 wt % aqueous sodium bisulfite solution (400 mL), water (1000 mL) and finally dried overnight at 500° C. under vacuum to afford 70.0 parts of compound (1) as a red solid. NMR—1H (DMSO-d6, 300 MHz, ppm): 8.2 (s, 1H), 8.2-8.1 (m, 2H), 7.8 (m, 2H).

The sequences of the Estradiol aptamer 25 and the split aptamer fragments were synthesized and purified by Purigo Biotech, Inc. (Taipei, Taiwan), as shown in Table 1. Estradiol, ethinylEstradiol, 1-aminoanthraquinone, 2-methoxynaphthalene, estrone, testosterone, and sodium chloride were obtained from Sigma-Aldrich (St. Louis, MO). Sigmatrix urine diluent, which mimics human urine, was also obtained from Sigma-Aldrich. Next, 20-nm AuNPs were purchased from BBI Solution (Madison, WI). All chemicals were of the analytical grade, and solutions were prepared using milliQ water (Millipore, Bedford, MA).
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.
