According Quote by Stefan Hell
“According to the belief, molecules closer together than 200 nanometers could not be told apart with focused light. This is because, in a packed molecular crowd, the molecules shout out their fluorescence simultaneously, causing their signal, their voices, to be confused.”
About This Quote
Source Speech: Nobel Lecture, Stefan Hell, 2014
Molecules within 200 nm cannot be distinguished by conventional light because their fluorescence overlaps, causing signal confusion.
In simple terms: Close molecules blur together under light.
