Sealable Large Pore by DNA Origami on Lipid Membrane

preprint
submitted on 17.08.2020 and posted on 17.08.2020 by Shoji Iwabuchi, Ibuki Kawamata, Satoshi Murata, Shin-ichiro Nomura
Here, we report on the design and function of a membrane nanopore through a DNA origami square tube with a cross-section of 100 nm2 . When the nanopore is added onto the giant vesicle membrane, the permeation of hydrophilic fluorescent molecules was observed. It can be sealed by the existence of the four specific single strand DNAs. A controllable artificial nanopore should help to communicate the vesicle components with their environment
