Minute noble metal particles, such as gold nanoparticles have characteristic colour. In the case of gold the particles are red and have been used for centuries as pigments for ceramics and stained glasses. It has been recently discovered that these particles, when illuminated with visible light (e.g. sunlight) can cause chemical reactions that normally require high temperatures to occur under mild, room temperature conditions. This project aims at utilizing this unusual property of metal nanoparticles to reduce the energy required to carry out chemical transformations, such as those used to make organic molecules for pharmaceuticals, dyes and plastics.

微小的贵金属颗粒，例如金纳米颗粒，具有特征颜色。就金而言，颗粒是红色的，几个世纪以来一直被用作陶瓷和彩色玻璃的颜料。最近发现，这些颗粒在可见光（例如阳光）照射下会引起通常需要高温才能在温和的室温条件下发生的化学反应。该项目旨在利用金属纳米颗粒的这种不寻常特性来减少化学转化所需的能量，例如用于制造药物、染料和塑料有机分子的化学转化所需的能量。
