简介
SARS‐CoV‐2 has led to a worldwide pandemic, catastrophically impacting public health and the global economy. Herein, a new class of lipid‐modified polymer poly (β‐amino esters) (L‐PBAEs) is developed via enzyme‐catalyzed esterification and further formulation of the L‐PBAEs with poly(d,l‐lactide‐coglycolide)‐b‐poly(ethylene glycol) (PLGA‐PEG) leads to self‐assembly into a “particle‐in‐particle” (PNP) nanostructure for gene delivery. Out of 24 PNP candidates, the top‐performing PNP/C12‐PBAE nanoparticles efficiently deliver both DNA and mRNA in vitro and in vivo, presenting enhanced transfection efficacy, sustained gene release behavior, and excellent stability for at least 12 months of storage at −20 °C after lyophilization without loss of transfection efficacy. Encapsulated with spike encoded plasmid DNA and mRNA, the lipid‐modified polymeric PNP COVID‐19 vaccines successfully elicit spike …
