　　在HAuCl4-葡萄糖-丙酮体系中，丙酮不仅能起光敏剂、加速光化学还原Au(III)离子的反应，还能诱导已形成的金纳米粒子整形。整形过程伴随着明显的可见/近红外吸收光谱变化，并形成一些全新的纳米结构。实验结果表明，金纳米粒子的整形方式与初始金纳米粒子的形貌密切相关，对于球形的金纳米粒子，整形后形成纳米线；而对于锥形纳米粒子则形成金纳米片。

Acetone as a photosensitizer could not only accelerate the photochemical reduction reaction of Au(III), but also induce the reshaping of gold nanoparticles formed in HAuCl4-glucose-acetone solution system. The whole reshaping process was accompanied by the obvious Vis/NIR spectral changes of gold nanopartilces, finally, some new nanostructures were formed. The experimental results showed that the reshaping pattern was closely related to the original morphology of gold nanoparticles. Spherical gold nanoparticles were reshaped to gold nanolines, while gold nano-pyramids to nanodisk.
