Example 4

174 g of the methanol dispersion liquid of silver nanowire 2 (silver concentration: 0.2% by mass, dispersion medium: methanol, wire average diameter: 36 nm, average length: 20 μm) produced as above, was weighed in a 1000 ml eggplant flask. 3.1 g of 10% by mass PNVA aqueous solution (manufactured by Showa Denko K. K.), 40.9 g of propylene glycol (manufactured by Wako Pure Chemical Industries, Ltd.), and 112.3 g of PGME (manufactured by Tokyo Chemical Industry Co., Ltd.) were added thereto, and dispersed well. Thereafter, methanol was distilled away, by using an evaporator. Then, 63.2 g of pure water, 300 g of ethanol (manufactured by Kanto Chemical Co., Inc.), and 49.3 g of methanol (manufactured by Junsei Chemical Co., Ltd.) were added and stirred by using planetary centrifugal vacuum mixer Awatori Rentaro (registered trademark) ARV-310, manufactured by Thinky Corporation, to obtain silver nanowire ink 4 having a mass ratio between the binder resin (PNVA) and the silver nanowire (binder resin/silver nanowire) of 0.87.

Example 47

[HPSN(C2H4OC2H4OCH3)3Br]Ir Particle Complex

Into a two-neck flask (100 mL) equipped with a cooling tube, HPSNBr(C2H4OC2H4OCH3)3 (190 mg) and IrCl3.3H2O [manufactured by Furuya Metal Co., Ltd.] (84 mg) were charged and thereto, further ethanol [manufactured by Kanto Chemical Co., Inc.] (15 mL) and distilled water (15 mL) were added, followed by purging the inside of the flask with nitrogen. Under heating-reflux (80° C.), the resultant reaction mixture was stirred for 12 hours. After the reaction, the solution was filtered with a membrane filter and from the resultant filtrate, the solvent was distilled off with a rotary evaporator. The resultant residue was re-dissolved in chloroform [manufactured by Kanto Chemical Co., Inc.] (10 mL) and the resultant solution was dropped into hexane [manufactured by Kanto Chemical Co., Inc.] (30 mL) to subject the solution to re-precipitation purification. An ocher solid (192 mg) of an [HPSNBr(C2H4OC2H4OCH3)3]Ir particle complex was obtained. The Ir content was measured by a DTA-TG measurement and found to be 24.8% by mass. The result of the DTA-TG measurement is shown in FIG. 23. An image of the obtained black solid observed under TEM is shown in FIG. 24.

Mouse AFP in the P0 mouse serum and bovine AFP levels in FBS used in this study were measured in duplicate using enzyme-linked immunosorbent assay kits (R&D Systems, for mouse; Cloud-Clone, for cow) according to the manufacturer's instructions. For E2 measurement in FBS, ethyl acetate was added to FBS or standard E2 (Kanto Chemical) solution dissolved in methanol (Kanto Chemical), and then mixed and centrifuged at 16,000 g for 3 min at 4°C. This step was repeated three times. These supernatants containing E2 were combined and dried under a nitrogen stream. The solid was reconstituted in ethanol (Kanto Chemical) and subjected to liquid chromatography-tandem mass spectrometry (Nexera UHPLC; API 4000, AB SCIEX).

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.
