Solvatochromic fluorophores possess emission properties that are sensitive to the
nature of the local microenvironment. These dyes have been exploited in
applications ranging from the study of protein structural dynamics to the
detection of protein-binding interactions. Although the solvatochromic indole
fluorophore of tryptophan has been utilized extensively for in vitro studies to
advance our understanding of basic protein biochemistry, the emergence of new
extrinsic synthetic dyes with improved properties, in conjunction with recent
developments in site-selective methods to incorporate these chemical tools into
proteins, now open the way for studies in more complex systems. Herein, we
discuss recent technological advancements and their application in the design of
powerful reporters, which serve critical roles in modern cell biology and assay
development.
