Green Tea Antioxidant Helps Sneak RNA Drug into Cells

It’s called a “green nanoparticle”—not because it arises in nature, but because it incorporates a metabolite, an antioxidant, that is found in green tea. The green nanoparticle’s other component, a small polymer, is not so natural. It is low in toxicity, however, and it can complex with the antioxidant to form a unique drug delivery vehicle, one that can carry delicate RNA drugs safely across the cell membrane.By facilitating the efficiency of RNA drugs—specif
