(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.
Before taking effect, pharmaceuticals that target cell function must cross a crucial barrier: the complex assembly of lipids, proteins, and carbohydrates that make up biological membranes. Recently, scientists realized that ...
