摘要

金纳米棒具有局部表面等离子体共振吸收特性，在生物医学和传感领域具有重要的应用价值。采用银介导播种法制备金纳米棒，对制备的金纳米棒的纵向局部表面等离子体共振(LSPR)吸收进行了监测，并讨论了金纳米棒的生长动力学。结果表明:金纳米棒的生长过程为一级反应，其活化能约为54.4 kJ/mol;该实验结论为金纳米棒的制备及应用研究提供了良好的理论指导。

Study on the growth kinetics of Au nanorods based on local surface plasmon resonance

Gold nanorods are of great significance in biomedical and sensing applications due to their local surface plasmon resonance absorption. The silver-mediated seeding method was used to prepare gold nanorods, the longitudinal local surface plasmon resonance (LSPR) absorption of the prepared gold nanorods was monitored, and the growth kinetics of the gold nanorods were discussed. The results show that the growth process of gold nanorods is characterized by a first-order reaction, and its activation energy is about 54.4 kJ/mol. This experimental conclusion provides a good theoretical guide for the preparation of gold nanorods during application research.
