(Phys.org)—Researchers in Germany and the US have used scaffolded DNA origami techniques to create ion channels or pores that span and penetrate lipid membranes and mimic natural ion channels.
For the first time researchers succeeded to place a layer of graphene on top of a stable fatty lipid monolayer. Surrounded by a protective shell of lipids graphene could enter the body and function as a versatile sensor. ...
