A Coarse-Grained Simulation Framework to Study Polyethylenimine-DNA Nanoparticles in Gene Delivery
DownloadSpring 2022
Cellular DNAs contain genetic information vital for the functioning of the cells. Corruption of this information, or genetic disorders, can lead to various diseases. A potential treatment is to deliver exogenous DNAs with the correct genetic information to malignant cells to achieve a...

Molecular Dynamics Simulations of Polyethylenimine Mediated Nucleic Acid Complexation with Implications for Non-viral Gene Delivery
DownloadSpring 2013
Gene therapy is a promising therapeutic technique that involves delivering nucleic acids into cells. Polycations have evolved into a major category of gene carriers. Polyethylenimine (PEI) is one of the most effective polycationic carriers. Furthermore, modifying PEI with certain lipophilic...
