| 摘 要： | 以牛血清蛋白(bovine serum albumin,BSA)、氯金酸(HAuCl4)、NaOH等为原料,采用一锅合成法制备了牛血清蛋白-Au配合物(BSA-Au),观察到了样品的宽带红光荧光发射。通过库仑力作用将BSA-Au与表面带有正电荷的金纳米颗粒进行复合,对纳米复合物的吸收光谱及荧光光谱特性进行了研究。实验结果表明,在本实验条件下,金纳米颗粒虽然增强了复合物样品在可见光区域的光吸收,但对BSA-Au红光发光有猝灭作用。

| Abstract: | Bovine serum albumin(BSA)-Au complexes were synthesized by the one-pot method with BSA,HAuCl4 and NaOH as the starting materials.Red photoluminescence was observed from the sample.Au nanoparticle@BSA-Au composites were fabricated via the Coulomb interaction between the negatively charged BSA-Au and the positively charged Au nanoparticles.Optical absorption and photoluminesence properties of the samples were investigated.The experimental results show that optical absorption in the visible region was enhanced for the Au nanoparticle@BSA-Au composites,due to the localized surface plasmon resonance.However,the luminescence of BSA-Au was quenched.Further work on improving the structure of the Au nanoparticle@BSA-Au composites needs to be conducted. |
