“…[4] Formation-disruption of hydrogen bonds with solvent molecules and solvent-dependent changes of dye geometry can strongly alter fluorescence intensity and lifetime. [104][105][106] Dramatic fluorescence quenching may occur in water due to the formation by solute-solvent H-bonds. [106] In addition, the solvent can influence the dye energetics, particularly the inversion of n* (non-fluorescent) and π* (fluorescent) energy levels.…”

Fluorescence spectroscopy provides numerous methodological tools for structural and functional studies of biological macromolecules and their complexes. All fluorescence‐based approaches require either existence of an intrinsic probe or an introduction of an extrinsic one. Moreover, studies of complex systems often require an additional introduction of a specific quencher molecule acting in combination with a fluorophore to provide structural or thermodynamic information. Here, we review the fundamentals and summarize the latest progress in applications of different classes of fluorescent probes and their specific quenchers, aimed at studies of protein folding and protein‐membrane interactions. Specifically, we discuss various environment‐sensitive dyes, FRET probes, probes for short‐distance measurements, and several probe‐quencher pairs for studies of membrane penetration of proteins and peptides. The goals of this review are: (a) to familiarize the readership with the general concept that complex biological systems often require both a probe and a quencher to decipher mechanistic details of functioning and (b) to provide example of the immediate applications of the described methods.
