荧光和量子点的基本原理和发展历史

在您的科研生涯的某个时候,都有可能会用到荧光显微镜。这种无处不在的技术改变了显微镜学家对研究对象进行成像、标记和追踪的方式,不论是整个生物体,还是单个蛋白质等等。 通过本文,我们将探讨什么是“荧光”,包括其定义背后的历史和基础物理原理,绿色荧光蛋白(GFP)的发现和应用,并展望量子点等荧光探针不断扩大的应用领域。

柯勒照明:简史介绍和设置的5个简单步骤

在任何特定光学显微镜调试当中,柯勒照明都是实现最佳成像的最重要且最基本的技术之一。尽管柯勒照明应该视为显微镜设置的常规组成部分,但是许多显微镜学家认为正确的设置过于复杂耗时,因此仍然没有被广泛应用。充分了解显微镜的两个主要部件(光阑和载物台下聚光透镜)在实际操作中的调整后,正确的设置就只需要几分钟的时间。正确对齐的显微镜可以大大改善图像的均匀对比度和照明,从而获得更高的分辨率和观察到更多的细节。在…
