Insufficient endosomal escape presents a major hurdle for successful nucleic acid therapy. Here, the first time, chemical electron transfer (CET) system was integrated into small interfering RNA (siRNA) lipid nanoparticles (LNPs). The CET acceptor can be chemically excited using generated energy between donor and hydrogen peroxide, which triggers generation of reactive oxygen species (ROS), promoting membrane destabilization. Tetra-oleoyl tri-lysino succinoyl tetraethylene pentamine included as an ionizable lipopeptide with U-shaped topology effective siRNA encapsulation pH-induced escape. LNPs loaded components demonstrated more efficient escape, evidenced by galectin-8-mRuby reporter; ROS significantly augmented galectin-8 recruitment at least threefold compared control groups,
