| One-dimensional materials have an enormous potential as key components for nanoscale biological sensors. In spite of an obvious need for functional reconstitution of biomolecules in such devices to enhance their specificity and biocompatibility, robust strategies for noncovalent surface modification of 1-D materials are missing. Lipid bilayers in particular offer a very attractive platform for immobilizing biological molecules. We present a new way of 1-D materials modification based on polyelectrolyte layer-by-layer self-assembly followed by the lipid bilayer formation. We demonstrate our strategy by synthesizing one-dimensional lipid bilayers wrapped around carbon nanotubes. We also determine mobility of lipid molecules in these highly strained structures and present a diffusion model for quantitative description of their behavior. |
