The researchers packaged the mRNA with a degradable polymer, to trick the mice's lung cells into accepting the package.

研究人员用可降解聚合物包裹信核糖核，老的接受。

“By doing so, we could actually make the nanoparticles keep their functionality but make them degradable while also reducing the amount of the silver core in the nanoparticle system, ”

通过这种方法，我们既可以让纳米粒子发挥功效，也可以实现可降解，与此同时减少纳米颗粒中的银芯数量。
