With high-efficiency transfection and low cytotoxicity as the core, PEI·HCl empowers multiple fields:
Gene therapy: improves DNA/mRNA transfection efficiency, adapts to viral vector packaging and recombinant protein production; binds magnetic nanoparticles to enhance mRNA delivery, and is used for vaccine development;
Targeted delivery: Atomized inhalation system achieves lung-specific targeting and adapts to the treatment of respiratory diseases;
Diagnostic technology: As a PCR enhancer (Au/PEI nanoparticles), improve sensitivity and specificity; develop rapid detection kits (such as pathogen detection).
