Dendritic polymers encase coacervate microdroplets, enabling them to closely mimic natural cells

A stabilising sheath of interlocking polymers enables coacervate microdroplets to more closely mimic natural cells than ever before. The researchers behind the work showed how the protected coacervates can form part of a chemical signalling cascade with natural cells, and suggest that the technique could have applications in drug delivery and tissue engineering.
