DIC显微镜在复杂环境下的成像质质纳米粒子方面优于暗场。然而,DIC 也需要更多的知识和技能才能获得可重复的结果。DIC显微镜提供高横向分辨率和浅景深。
在监测细胞内或复杂环境中的纳米粒子时,这两种特性都极为重要。首先,使用划线笔在每个玻璃盖玻片的中心放置一个浅和短的划痕,然后清洁玻璃,如随附的文本协议中所述。接下来,使用微移器从原始存储容器中去除 100 微升的 05 毫克每毫升金纳米颗粒溶液,然后将溶液喷射到 1.5 毫升离心管中。
在6000倍的重力下将样品离

Summary
该协议的目的是详细介绍一种经过验证的制备等离子体纳米颗粒样品的方法, 以及用差分干涉对比度 (DIC) 显微镜对其进行单粒光谱的方法。
