Mechanically Triggered DNA Nanovehicles for Targeted Dual‐Drug Cancer Therapy

Advanced Science, EarlyView.
A mechanically triggered DNA nanovehicle is introduced that co‐releases two anticancer drugs in response to integrin‐mediated cellular forces. Cholesterol‐anchored DNA assemblies undergo force‐induced unfolding at cell–cell junctions, enabling selective, localized dual‐drug activation in cancer cells while minimizing off‐target toxicity in low‐tension ...
