to 3.0 mol dm−3. As a result, strontium sulfite crystals were obtained in the following four forms: spherical, poly-spherical, ellipsoidal, and spindle. The cause of the crystalform change was found to be a difference in the growth side by comparison of X-ray diffraction patterns. In addition, the optimum conditions which controlled the crystalform were influenced by the pH value in the gel and the
improved pharmacokinetics properties compared to their organic counterparts. Here we introduce strontiumsulfite nanoparticles as new pH-responsive inorganic nanocarriers for efficient transport of siRNAs into breast cancer cells. We employed the simplest nanoprecipitation method to generate the strontiumsulfite nanoparticles (SSNs) and demonstrated the dramatic roles of NaCl and d-glucose in particle
