A bubbly personality: Coalescence and fusion of carbon dioxide nanobubbles in a tumor leads to microbubbles that can be imaged by ultrasound (see picture). The bubbles are released from gas‐generating polymericnanoparticles that are coated with hydrophobically modified chitosan. Hydrolysis of the polymer poly(BL‐PO), which consists of a biodegradable main backbone and a carbonate side chain, results
