黑尔的理论文章并没有立即引发轰动,但因足够有趣,他得以进入马克斯·普朗克生物物理化学研究所工作。在随后的几年中,他研制出一个STED显微镜,并在2000年以光学显微镜从未达到的分辨率获得了大肠杆菌的图像,用实践证明了自己的理论。
威廉·莫纳:探测单个荧光分子的*人
大多数的化学方法,例如测量荧光,科学家需要同时研究数百万个分子。很长一段时间里,他们都在梦想能够测量单个分子,因为获得的认知越丰富、越详尽,理解就越深入,比如疾病是发展的。因此,1989年,当在IBM研究中心工作的威廉·莫纳成功地测量了单个分子的光吸收时,他也为单分子显微镜的发展奠定了基础。他的实验启发了许多化学家们将目光投向单个分子,其中就包括埃里克·贝齐格。
1997年,莫纳进入加州大学圣地亚哥分校,开始了让绿色荧光蛋白呈现彩虹的所有颜色的研究。他发现,绿色荧光蛋白的一个变体发出的荧光可被随意地开启和关闭——当受到波长488纳米的光激发时,蛋白开始发出荧光,但不久就会逐渐熄灭。他将这些蛋白质分散到凝胶中,并让它们之间的距离大于0.2微米的阿贝衍射极限。在常规光学显微镜下,可以看到单个分子的光,它们就像一盏盏带开关的小灯。
Hare's theoretical essay did not immediay provoke a sensation, but because of enough interest, he was able to enter the Max Planck Institute for Biophysical and Chemical work. In subsequent years, he developed a STED microscope and obtained the image of Escherichia coli at an unprecedented resolution with a light microscope in 2000, which proved his own theory.
William Mona: The first person to probe a single fluorescent molecule
Most chemical methods, such as measuring fluorescence, require scientists to study millions of molecules simultaneously. For a long time, they all dreamed of being able to measure a single molecule because the more cognitive and acquired, the more detailed the understanding, the more in-depth understanding, such as the development of the disease. So, when William Mona, working at the IBM Research Center, successfully measured the light absorption of a single molecule in 1989, he laid the groundwork for the development of single-molecule microscopy. His experiments inspired many chemists to turn their attention to individual molecules, including Eric Bezig.
In 1997, Mona entered the University of California, San Diego, and began researching all the colors that make GFP rainbow. He found that the fluorescence emitted by a variant of a green fluorescent protein could be turned on and off as desired - the protein started to fluoresce when excited by light at a wavelength of 488 nm, but soon extinguished. He spreads these proteins into the gel with a distance between them greater than the Abbe diffraction limit of 0.2 microns. Under a regular light microscope, you can see a single molecule of light that resembles a small light with a switch.
