原声例句
精选英语短文 Nanoparticles suspended in liquids are widely used (known as colloidal gold) and their color, from deep red to pale blue, is a visual guide to their relative size. 悬浮在液体中的纳米颗粒被广泛使用(称为胶体金), 它们的颜色, 从深红色到淡蓝色, 是它们相对大小的视觉指南。
中文百科
奈米黄金![]() ![]() ![]() ![]() 奈米黄金或奈米金(英语:nanogold),又称胶态金(colloidal gold),因为它在空气中容易聚集成为块材黄金,所以一般都把奈米黄金制备在溶液系统中。胶态金水溶液呈现悬浮溶液的特色,溶液中金颗粒大小约在次微米尺寸(小于1微米)。在溶液中,尺寸大小低于100奈米的胶态金粒子常致使溶液带有强烈的红色,而尺寸大小高于100奈米的胶态金粒子则使溶液呈蓝色或紫色。 由于金奈米粒子特殊的光学性质、电子性质、分子识别性质与良好的生物兼容性,使纳米黄金成为了最广泛被研究的金属奈米材料,目前已应用于各种不同领域,如电子显微镜学、电子学、材料科学、奈米科技、生化传感、光学侦测、药物投递、催化反应、疾病治疗、电子工程以及模板结晶等。
英语百科
Colloidal gold 奈米黄金![]() ![]() ![]() ![]() Colloidal gold is a sol or colloidal suspension of submicrometre-size nanoparticles of gold in a fluid, usually water. The liquid is usually either an intense red colour (for particles less than 100 nm) or blue/purple (for larger particles). Due to the unique optical, electronic, and molecular-recognition properties of gold nanoparticles, they are the subject of substantial research, with applications in a wide variety of areas, including electron microscopy, electronics, nanotechnology, and materials science. |
