Fig. 2From: Hydralazine loaded nanodroplets combined with ultrasound-targeted microbubble destruction to induce pyroptosis for tumor treatmentCharacteristics of (HYD-)NDs. (A) (HYD)-NDs synthesis diagram. (B) HYD-NDs’ TEM scans under pH 7.4 conditions. (C) HYD-NDs’ TEM scans under pH 6.5 conditions. (D) The HYD-NDs’ size distribution under pH 7.4 conditions. (E) Comparison of the HYD-NDs size distribution over varied pH environments (0.5 h). (F) Size distribution comparison of HYD-NDs over diverse pH enviroulents (4 h). (G) Zeta potential of HYD-NDs over diffirent pH settings. (H) Drug release of HYD-NDs at varied pH settings. (I) HYD-NDs’ medication release profile when exposed to ultrasound.
