Activation of the stimulator of interferon genes (STING) can induce immunity in various cancer therapies, but delivery of STING agonists to tumours is challenging. Now a metal-based polymeric nanoparticle delivers STING agonists to tumours upon disruption of endothelial cells in tumour vasculature and targets tumour-associated macrophages, eliciting anti-tumour immune response in hard-to-treat cancer models.
