1/9 Could graphene coverslips improve your single-molecule fluorescence and superresolution experiments? In our article in @AdvancedAms we combine #DNAorigami with #graphene to perform #singlemolecule #biophysics, #biosensing & #superresolution microscopy.

2/9 Graphene is almost transparent and quenches fluorescence in a range of ~40 nm. Fluorescence intensity or fluorescence lifetime of single molecules directly tell you the distance of a molecule to the surface. Differences in the z-direction as small as 2.9 nm are resolved. 
3/9 Dynamics with graphene energy transfer (GET). We use GET to visualize motion on top of a graphene surface and determine the timescale of fluctuations via autocorrelation analysis.
