Abstract
The permeability of polymer vesicles that contain membrane-embedded catalytic particles can be regulated upon exposure to a catalyst reactant.

Giant polymer vesicles which have membrane-embedded catalytically active manganese oxide particles are made using dropletbased microfluidics
A vesicle is a self-contained body of liquid surrounded by a lamellar, often bilayer-type, membrane dispersed in a liquid environment
Summary
Compartmentalization of small and finite volumes of liquids and the consecutive emergence of membrane bioenergetics are identified as being of key importance in the evolution of cells, and the origins of life.[1] The ability to mediate transport across a cell membrane is crucial for cellular activity, from regulation of ion transport to uptake of nutrients.[2] In eukaryotic and prokaryotic cells, functional proteins embedded in the cell membrane regulate transport of ions and molecules and are known as transmembrane proteins (TMPs) This concept of having the ability to regulate and control membrane permeability on demand is being explored in a variety of scientific fields, using a range of both biological and chemical methods.[3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29]
