Abstract

Gold nanomaterials have received much attention in sensing due to their unique optical and electronic properties. This article briefly summarized the synthesis, property of gold nanomaterials before focusing on their application to sensing. The synthesis of three major types of gold nanomaterials is discussed: gold nanoclusters, which are synthesized by templated method, and gold nanoparticles, which are synthesized by chemical reduction methods, and gold nanorods, which are synthesized by the seed-mediated method. More methods affecting nano properties are discussed. Properties of these gold nanomaterials are usually connected to their application. Their fluorescent, photoluminescent, chemiluminescent, electrochemiluminescent, and catalytic properties are what give them potential in sensing. For the further application of gold-based nanomaterials in sense, the author suggests that more research needs to be done on understanding their properties and surface functionalization which provide greater selectivity and sensitivity in sense. Moreover, new detection techniques need to be developed to improve detection accuracy and reduce operational complexity.

用于生化传感的金纳米材料

摘要纳米金材料以其独特的光学和电子特性在传感领域受到广泛关注。本文简要介绍了金纳米材料的合成、性质及其在传感领域的应用。讨论了三种主要金纳米材料的合成方法:模板法合成的金纳米团簇、化学还原法合成的金纳米粒子和种子介导法合成的金纳米棒。讨论了影响纳米性能的其他方法。这些金纳米材料的性质通常与其应用有关。它们的荧光、光致发光、化学发光、电化学发光和催化性质使它们在传感方面具有潜力。对于金基纳米材料在意义上的进一步应用，作者建议在了解其性质和表面功能化方面做更多的研究，以提供更大的选择性和灵敏度。此外，需要开发新的检测技术来提高检测精度和降低操作复杂性。图形抽象

期刊介绍： Gold Bulletin is the premier international peer reviewed journal on the latest science, technology and applications of gold. It includes papers on the latest research advances, state-of-the-art reviews, conference reports, book reviews and highlights of patents and scientific literature. Gold Bulletin does not publish manuscripts covering the snthesis of Gold nanoparticles in the presence of plant extracts or other nature-derived extracts. Gold Bulletin has been published over 40 years as a multidisciplinary journal read by chemists, physicists, engineers, metallurgists, materials scientists, biotechnologists, surface scientists, and nanotechnologists amongst others, both within industry and academia. Gold Bulletin is published in Association with the World Gold Council.
