PDI images of New Zealand rabbit kidney. (a) The image was black before the intravenous injection of nanobubbles in rabbit. (b) After intravenous injection of the nanobubbles, PDI enhancement was observed. (c) In vitro contrast enhanced US imaging showed the gray-scale intensities of siRNA-NBs decreased more slowly than the gas-cored liposomes [18, 19].
