(Resomer X 206S, inherent viscosity
2.0, Mw = 1.01 × 105 g/mol)
was purchased from Evonik, Germany. KCG and FUC were bought from Sigma-Aldrich.
1,1,1,3,3,3-hexafluoroisopropanol (HFIP) purchased from FluoroChem,
was used as received. The Milli-Q water used in this study was drawn
from a Millipore Direct Q8 system (Millipore, Schwalbach, with Millimark
Express 40 filter, Merck, Germany) with a resistivity of 18.0 MΩ
cm. Phosphate buffer tablets (PBS) were purchased from VWR Life Sciences
and PBS solution was prepared by dissolving one tablet in 100 mL of
Milli-Q water.
