Abstract

Manganese powder with a suitable potential (, -1.19 V) has never been investigated for the reduction of Au (, 1.00 V). In this study, we have utilized and low pH dependent for the polyethylene glycol stabilized gold nanoprism synthesis by reducing AuCl in the presence of thiol terminated polyethylene glycol as the stabilizing agent. The synthetic methodology for gold nanoprisms has been optimized by pH and Cl ion combination. Time dependent absorbance studies have been conducted to demonstrate the role of various reaction parameters such as the stabilizing agent, HCl concentration, temperature, and Mn metal. The synthesized gold nanoprism has been further utilized as a seed for nucleic acid and selected amino acid mediated edge and surface growth, respectively.

摘要

具有合适电位（-1.19 V）的锰粉从未被用于研究其对金（1.00 V）的还原作用。在本研究中，我们利用了在低pH条件下，以硫醇封端的聚乙二醇作为稳定剂，通过还原AuCl来合成聚乙二醇稳定的金纳米棱。通过pH值和氯离子组合优化了金纳米棱的合成方法。进行了随时间变化的吸光度研究，以证明各种反应参数的作用，如稳定剂、HCl浓度、温度和锰金属。合成的金纳米棱已进一步分别用作核酸和选定氨基酸介导的边缘和表面生长的种子。
