| Résumé | The transport of mRNA plays an indispensable role in vaccine drug delivery and emerging therapies. The attachment of lipid nanoparticle encapsulating mRNA (mRNA-LNP) to biological and engineering surfaces is determined by their intermolecular and surface interactions. In this work, the interactions between mRNA-LNP and surfaces with various functional groups were investigated using atomic force microscopy. The results show that mRNA chains are coiled in LNPs, and the surface charges of mRNA are screened by the surrounding lipid molecules. Approach force curves demonstrate that the steric repulsion varies with functional groups. Force mapping reveals that the intermolecular interactions, i.e., hydrogen bonding and electrostatic interaction, contribute to the adhesion. The –OH group is suggested as the most probable binding site for mRNA-LNP attachment. This work provides new insights into mRNA transport mechanisms at biological and engineering surfaces, with useful implications for designing novel nanocarriers and developing functional surfaces for biological applications. |
