H2HUBB TAKEAWAY
In cancer cells, the asymmetric PAA-AB@PDA NPs selectively scavenge cytotoxic ·OH, thereby disrupting the redox homeostasis, which in turn leads to mitochondrial damage and reduced ATP production. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
