封面特征显示了由浸入pH 12的碱性上清液中的非离子聚丁二烯-b-聚环氧乙烷两亲嵌段共聚物形成的聚合物囊泡（聚合物囊泡）。聚合物囊泡在pH 2的水溶液中负载有水溶性染料。聚合物囊泡的坚固稳定的膜能够有效地维持10个单位的pH梯度至少8天。这是工程成功的仿生系统的基本特征。更多信息可在L. Ruiz-Pérez et al. on page 1987 in Issue 16，2018（DOI：10.1002/cphc. 201800187）。
The Cover Feature shows polymeric vesicles (polymersomes) formed by non-ionic polybutadiene-b-polyethylene oxide amphiphilic block copolymers immersed in an alkaline supernatant at pH 12. Polymersomes are loaded with a water soluble dye in aqueous solution at pH2. The polymersomes’ robust and stable membranes are able to efficiently sustain pH gradients of 10 units for a minimum of 8 days. This is an essential feature for engineering succesful biomimetic systems. More information can be found in the Communication by L. Ruiz-Pérez et al. on page 1987 in Issue 16, 2018 (DOI: 10.1002/cphc. 201800187).
