New strategy for mRNA nanocarriers using triphenyl phosphonium

Among the vastly different ways of tackling a disease, controlling the genetic expression of cells is undoubtedly one of the most powerful. Over the past few decades, scientists have come up with dozens of innovative strategies that involve using messenger RNA (mRNA) to 'force' cells to build specific proteins. These mRNA-based therapies have recently gained prominence as vaccines against infectious diseases like COVID-19. Additionally, they hold significant potential for treating cancer and genetic disorders.
