摘要
近年,食品安全问题逐渐受到重视,食品安全检测方法除了常用的简单化学分析、仪器分析,还发展出一些新兴检测方法如纸基微型分析系统等,但均有一定局限性。本研究综述了DNA介导的金纳米材料在食品安全检测领域的研究进展,DNA作为一种覆盖剂,被应用于介导金属纳米粒子种子形态的转变和性能的增强,其中金纳米性质最为优良;介绍了其形成机制,系统地总结了由物理吸附和硫代DNA介导的具有不同形态的金纳米材料,并介绍了这些材料的稳定性、识别特性、光学特性、催化特性、生物相容性及其生物传感应用。本研究为DNA介导的纳米材料的生长及其在生物传感等领域的应用奠定了基础。
In recent years,food safety issues have gradually gained attention.In addition to commonly used methods like simple chemical and instrumental analysis,novel detection techniques including paper-based microanalytical systems have developed.Nevertheless all of these methodologies possess certain limitations.This paper provides a comprehensive overview of the research progress of DNA-mediated gold nanomaterials in the field of food safety detection.DNA,as a covering agent,has been applied to mediate the morphological transformation and performance enhancement of metal nanoparticles,in which gold nanoparticles exhibit excellent properties.This review presented the formation mechanism,systematically summarized diverse gold nanomaterials mediated with different forms mediated by physical adsorption and thiolated DNA,and elucidated their stability,recognition properties optical characteristics,catalytic activities,biocompatibility,and biosensing applications.This paper lays the foundation for the growth of DNA-mediated nanomaterials and their applications in fields such as biosensing.
