The synthesis of artificial cell is a route for searching the origin of protocell. Here, we create a novel cell model of graphene capsules with selective ion channels, indicating that graphene might be an embryo of protocell membrane. Firstly, we found that the highly oxidized graphene and phospholipid-graphene oxide composite would curl into capsules under(More)
Many signs indicate that the graphene could widely occur on the early Earth. Here, we report that coating graphene oxides with phospholipid would curl into capsules in saturated solution of heavy metal salt of pH 0.15 at 4 o C similar to the primitive ocean conditions. L-animi acids exhibit higher reactivity than D-animi acids for graphene oxides. Moreover,(More)
