In the vast microscopic world contained within the human body, a universal component of all cell membranes is known as a lipid bilayer, a biological membrane consisting of two layers of lipid molecules. As it is highly impermeable large molecules and small polar molecules cannot cross the cell membrane, without the assistance of other structures. To allow the transport of macromolecules and ions across the … Continue reading Synthetic DNA nanopore selects and transports macromolecules across cell membranes.
