摘要

约翰内斯·伯格(Johannes Berg)的封面展示了海藻酸钙的示意图，它由甘露醛酸(绿色)和古鲁醛酸(红色)组成，由钙阳离子(黄色)交联。互穿的附加聚合物是聚乙烯亚胺(蓝色)，从而构成复合水凝胶。带正电的亚甲基蓝由于其带负电的聚合物骨架而被选择性地吸附在海藻酸盐水凝胶中。同时，带负电的刚果红被带正电的聚亚胺选择性吸附。(DOI: 10.1002 / pol.20230215)

The cover by Johannes Berg shows the schematic representation of calcium alginate consisting of mannuronic acid (green) and guluronic acid (red), cross-linked by calcium cations (yellow). An interpenetrating additional polymer is polyethyleneimine (blue), thereby constituting a composite hydrogel. Positively charged methylene blue is selectively adsorbed in the alginate hydrogel due to its negatively charged polymer backbone. Along with that, negatively charged congo red is selectively adsorbed by the positively charged polyethyleneimine. (DOI: 10.1002/pol.20230215)
