제목 Multi-layer coated nanoparticles for delivery of oligonucleotides into multidrug-resistant bacteria
초록 Bacterial infections have been a major cause of mortality worldwide. The overuse of broad-spectrum antibiotics has given rise to the emergence and spread of antibacterial resistance, which has become a serious threat to public health. Nanoparticle-based gene delivery systems that inhibit the expression of target genes provide an alternative treatment option in combating multidrug-resistant bacterial infections with high selectivity. Multi-layer coated gold nanoparticles (AuNPs) were prepared by sequential modification of AuNPs with polyethyleneimine (PEI) and oligonucleotides. The multi-layer coated AuNPs were efficiently taken up into MRSA and resulted in inhibition of bacterial growth. This study presents a novel application of gene delivery systems in the treatment of multidrug-resistant bacterial infections that can overcome limitations of conventional antibiotics.
