Fig. 3From: On-demand pH-sensitive surface charge-switchable polymeric micelles for targeting Pseudomonas aeruginosa biofilms developmentThe variations in Zeta potentials (a) and particle sizes (b) of SCSMs and SCUMs vs time under pH 7.4 and 5.5, respectively. Error bars denote the standard deviations. TEM images of SCSMs after incubation at pH 5.5 for 0.5 h (c) and 8 h (d). Scale bars = 200 nm. n = 3 for all researchBack to article page
