Surfactant exchange performed on a HexCoil-Ala-SWCNT sample subjected to an excess of (a) SDBS and (b) sodium cholate at 60 °C for 10 minutes of incubation. For comparison, SDBS exchange is performed on samples of (c) (GT)30-SWCNT or (d) (TAT)4TSWCNT under the same conditions. (e) Binary dispersions of SDBS with (GT)30, (TAT)4T, or HexCoil-Ala. The peak position gives an indication of the relative binding strength of the biopolymer; a blue shift represents replacement by the surfactant molecule.
