“…However, CHAPS and the deoxycholates are known to provide relatively more nonpolar and hydrophobic environments to their guest molecules in comparison to the cholates. 50,51 Surprisingly, unlike this usual observation, which is true for most of the small fluorophores, in this study, however, there is only a marginal difference in the emission energy of curcumin between the deoxycholates, CHAPS, and cholates. Almost similar emission energies have also been observed for curcumin in the presence of high concentrations of NaC and NaDC (≈42 mM) in the literature.…”

“…Similar observation in the thermodynamic parameters has been observed for curcumin in the presence of SB-16 ( N -hexadecyl- N , N -dimethylammonio-1-propanesulfonate), a conventional zwitterionic surfactant . From the temperature-dependent fluorescence studies, it was observed that the fluorescence quantum yield and average lifetime of curcumin decrease with increasing temperature for all the surfactants (Table S3 and Figure S9), which can be attributed to the enhanced non-radiative decay processes due to the formation of fluffier micelles with less rigid interior at elevated temperatures. , …”
