Embodiment 1
[0022] Example 1 Preparation of novel core-shell structured nanoparticles
[0023] The preparation process is as figure 1 As shown, the steps are as follows:
[0024] (1) Preparation of nano gold rods: at room temperature, 10ml of 0.1mol L -1 The CTAB solution was added to the container (20ml round bottom flask), and then 50ul of 50mmol·L -1 HAuCl 4 solution, stirred rapidly for 1 minute; then quickly added 0.6ml of 10mmol·L -1 NaBH 4 The solution was stirred rapidly for 1 minute to obtain seed crystals;
[0025] 30ml of 0.1mol·L -1 Add the CTAB solution in another container (50ml round bottom flask), stir at an appropriate speed (add while stirring, to mix evenly), add 234ul of 50mmol L -1 HAuCl 4 solution, and then add 234ul of 10mmol·L -1 Silver nitrate solution, then add 150ul of 0.1mol L -1The L-AA solution (ascorbic acid solution), now the solution changed from light yellow to colorless, finally added 90ul seed crystals, stirred for 1 minute, and left to stand...
Embodiment 2
[0032] Example 2 Preparation of novel core-shell structured nanoparticles
[0033] Proceed as follows:
[0034] (1) Preparation of nano gold rods: at room temperature, 15ml of 0.1mol L -1 The CTAB solution was added to the reaction vessel (20ml round bottom flask), and then 80ul of 50mmol L -1 HAuCl 4 solution, stirred rapidly for 1 minute; then quickly added 1.0ml of 10mmol·L -1 NaBH 4 The solution was stirred rapidly for 1 minute to obtain seed crystals;
[0035] 40ml of 0.1mol·L -1 The CTAB solution was added to another reaction vessel (50ml round bottom flask), under stirring at an appropriate speed (adding while stirring, to mix evenly), add 250ul of 50mmol L -1 HAuCl 4 solution, and then add 250ul of 10mmol·L -1 Silver nitrate solution, then add 180ul of 0.1mol L -1 The L-AA solution (ascorbic acid solution), now the solution changed from light yellow to colorless, finally added 90ul seed crystals, stirred for 1 minute, and left to stand for 4 hours, the solutio...
Embodiment 3
[0039] Example 3 Preparation of novel core-shell structured nanoparticles
[0040] Proceed as follows:
[0041] (1) Preparation of nano gold rods: at room temperature, 12ml of 0.1mol L -1 The CTAB solution was added to the reaction vessel (20ml round bottom flask), and then 60ul of 50mmol L -1 HAuCl 4 solution, stirred rapidly for 1 minute; then quickly added 0.8ml of 10mmol·L -1 NaBH 4 The solution was stirred rapidly for 1 minute to obtain seed crystals;
[0042] 35ml of 0.1mol·L -1 The CTAB solution was added to another reaction vessel (50ml round bottom flask), under stirring at an appropriate speed (adding while stirring, to mix evenly), add 240ul of 50mmol L -1 HAuCl 4 solution, and then add 240ul of 10mmol·L -1 Silver nitrate solution, then add 170ul of 0.1mol L -1 The L-AA solution (ascorbic acid solution), now the solution changed from light yellow to colorless, finally added 90ul seed crystals, stirred for 1 minute, and left to stand for 4 hours, the solutio...
