smFRET decides the FRET among two fluorophores in a single receptor molecule at place temperature, enabling the receptor to transition between diverse conformational states in the course of the experiment. The labels for smFRET are bulkier than those for DEER and will for that reason report diverse conformational variations https://thegreatbookmark.com/story18229327/new-step-by-step-map-for-what-are-pain-receptors
