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 polymeric nanoparticles 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
起泡的性格:肿瘤中二氧化碳纳米气泡的聚结和融合会导致可通过超声成像的微气泡(见图)。气泡从被疏水改性的壳聚糖包被的产气聚合物纳米颗粒中释放出来。由可生物降解的主骨架和碳酸盐侧链组成的聚合物聚(BL-PO)的水解导致二氧化碳的释放。
