At a nano-level, optical properties of gold are unique and gave birth to an emerging platform of nanogold-based systems for diverse applications, because gold nanoparticle properties are tunable as a function of size and shape. Within the available techniques for the synthesis of gold nanoparticles, the radiolytic synthesis allows proper control of the nucleation process without the need for reducing agents, in a single step, combined or not with simultaneous sterilization. This review details and summarizes the use of radiation technologies for the synthesis and preparation of gold nanoparticles concerning fundamental aspects, mechanism, current pathways for synthesis and radiation sources, as well as briefly outlines final applications and some toxicity aspects related to nanogold-based systems.
在纳米尺度上,金的光学性质独特,催生了一个基于纳米金的新兴系统平台,可用于多种应用,因为金纳米颗粒的性质可根据尺寸和形状进行调节。在现有的金纳米颗粒合成技术中,辐射合成能够在无需还原剂的情况下,一步实现对成核过程的适当控制,可单独进行,也可与同时灭菌相结合。本文详细综述并总结了辐射技术在金纳米颗粒合成与制备中的应用,涉及基本原理、机制、当前合成途径和辐射源,还简要概述了最终应用以及与基于纳米金的系统相关的一些毒性问题。
