Fig. 2. (A) Library of amphiphilic di- and triblock copolymers 6–11 and (B/C) their utility as surfactants for PFC nanoemulsions composed of 7 : 3 v/v% perfluorodecalin (PFD, 12) : perfluorotripropylamine (PFTPA, 13). (B) Initial size distributions of POx-stabilized emulsions. Emulsions were prepared by sonicating a solution of 2.8 wt% surfactant with 10 vol% 7 : 3 PFD : PFTPA in phosphate buffered saline (PBS). Emulsions were diluted 1 : 100 in MilliQ water prior to measurements by dynamic light scattering (DLS). Data represents the average of three independent samples; error bars represent the half-width at half-maximum averaged over the three independent samples. (C) Ostwald ripening of emulsions over 60 days monitored by LS, see Fig. S7–S9† for raw data. Error bars represent the standard deviation of percent size changes for three independent samples.
