논문초록 In this study, we investigate the behavior of an amphiphilic single-stranded DNA (U4T), comprised of both hydrophilic and lipophilic segments (lipid-modified DNA), through molecular dynamics (MD) simulation. Our findings reveal the spontaneous self-assembly of U4T, forming spherical micelles with a lipophilic core in aqueous environments. Furthermore, we explore the implications of U4Ts on cell permeability, elucidating their interaction with lipid-modified DNA and cell membranes. Through coarse-grained (CG) simulations, we observe the aggregation of U4Ts, which persist throughout the simulation, highlighting their robust self-assembling properties. Additionally, both all-atom (AA) and CG simulations demonstrate the interaction between U4Ts and DOPC bilayers, with U4Ts effectively docking into the bilayer and maintaining stability over time. Our findings underscore the potential of U4Ts to aggregate into stable micelles and interact with cellular membranes, offering insights into their promising applications.
