Figure 1: Single-turnover detection of single-molecule reaction.

From: Single-molecule chemical reaction reveals molecular reaction kinetics and dynamics

Figure 1

(a) Experimental design of single-molecule chemical reaction: a single-resorufin molecule locked in a porous hollow SiO2 nanosphere was reduced by NaBH4 to non-fluorescent dihydroresorufin, which was then oxidized back to fluorescent resorufin by oxygen. (b) A segment of a typical single-molecule trajectory of fluorescence for the repeated redox process of a single dye molecule. The binning is 50 ms.
