当金遇到纳米——从大众的宠儿到科学家的掌上明珠
|
摘要
金因稀有、性质稳定,长期以来被用作首饰、货币和金融储备,也因此未能在化学领域得到有价值的应用。但将单质金分散为纳米尺度的粒子时,却因其表面效应、小尺寸效应等具备了多种特殊的物理、化学、生物特性。介绍了纳米金粒子的制备、性质,并重点从技术原理的角度综述了纳米金粒子在疾病筛查与诊断、DNA识别与检测、食品安全检测、高效及绿色催化方面的应用,包括免疫学、生物化学、催化化学等多个领域。
Because of its rare and stable nature, gold has long been used as jewelry, currency and financial reserves, and therefore has not been applied in the chemical field. However, when gold is dispersed into nanoscale particles, it has many special physical, chemical and biological characteristics because of its surface effect and small size effect. The preparation and characteristics of gold nanoparticles are introduced. The applications of gold nanoparticles in disease screening and diagnosis, DNA recognition and detection, food safety detection, efficient and green catalysis are reviewed from the perspective of technical principles, including immunology, biochemistry, catalytic chemistry and other fields.
