本文报道了一种在微波辅助下在玻璃基片上快速沉积连续金薄膜的方法。在微波辐射下，胶体溶液中的金纳米颗粒能够在几分钟内组装在裸露的基底上形成金单层。通过AFM获得的图像显示，在裸玻璃表面上形成的单分子层与用（3-氨丙基）-三甲氧基硅烷预硅烷化的玻璃基底上形成的单分子层基本相同。以该单层作为种子，因此可以在表面上进一步沉积金金属，并且沉积的金的厚度与正常无电镀的情况一样是时间依赖性的。在玻璃上制备50 nm金膜的总时间约为15分钟，比现有的化学镀方法短得多。电化学实验表明，所制备的金膜是连续的，可以作为稳定的电极，能够维持数百次的氧化还原循环。通过表面等离子体共振成像（SPRI）研究也验证了膜的质量，并且获得了相当清晰的蛋白质点的图片，显示制备了光滑的金表面和适当的膜厚度。
A microwave-assisted method for rapid deposition of continuous gold films on glass substrates has been developed. Under microwave irradiation, gold nanoparticles in colloidal solutions were shown able to assemble on the naked substrates to form a gold monolayer within minutes. Images obtained by AFM revealed that the monolayer formed on the naked glass surface was much the same as that formed on the glass substrates pre-silanized with (3-aminopropyl)-trimethoxysilane. With this monolayer as seeds, further deposition of gold metal on the surface was thus possible and the thickness of the deposited gold was time-dependent as in the case of normal electroless plating. The sum time for preparing a 50-nm gold film on glass was about 15 minutes, much shorter than the existed electroless methods. Electrochemical experiments showed that the prepared gold films were continuous and can be used as stable electrodes able to sustain several hundreds of redox circulation. The quality of the films were also verified by surface plasmon resonance imaging (SPRI) studies and quite sharp pictures of protein dots were obtained, showing a smooth gold surface and proper film thickness were prepared.
