A two-tiered Ag nanoparticle containing a cavity at the center of each nanoparticle is generated by two simple steps of nano-imprinting and metal vacuum deposition. It enables sub-zeptomole detection of organic molecules and five orders of the dynamic sensing range.
通过纳米压印和金属真空沉积两步简单的步骤,生成了一种双层 Ag 纳米颗粒,每个纳米颗粒的中心都有一个空腔。它能够实现亚zeptomole 级别的有机分子检测和五个数量级的动态检测范围。
