Breathing Polymersomes: CO2-Tuning Membrane Permeability for Size-Selective Release, Separation, and Reaction

Take a deep breath: The membrane permeability and the scale of membrane nanochannels of polymer vesicles are modulated by CO2 control of vesicular expansion and contraction. These polymersomes can act as size‐selective nanoseparators for particle sieving and as nanoreactors for enzymatic reactions t...

Description
Summary:	Take a deep breath: The membrane permeability and the scale of membrane nanochannels of polymer vesicles are modulated by CO2 control of vesicular expansion and contraction. These polymersomes can act as size‐selective nanoseparators for particle sieving and as nanoreactors for enzymatic reactions that require compartmentalization. GSH=glutathione.
