Fig. 1: Schematic of the sensing mechanism and the chemical structures of relevant compounds.
From: Two-photon fluorescence imaging and specifically biosensing of norepinephrine on a 100-ms timescale
a Schematic illustration of the ultrafast sensing mechanism toward norepinephrine by the two-photon fluorescence probe BPS3, boosted by the dual acceleration of conformational-folding and water-bridging. b Molecular structures of the compounds referred in this work.
