Figure 4: ΞΎ Potential and pore size as function of pH.
From: Biomimetic block copolymer particles with gated nanopores and ultrahigh protein sorption capacity
(a) ΞΎ potential of particles versus pH. (b) SEM images of the particles at different pH. With increase of pH, the size of the pores gradually decreases. Scale bars represent 1βΞΌm.
