although destabilization of these nanocarriers is required for efficient release when they reach target sites. To develop efficient polymeric nanocarriers, we intended to synthesize and characterize a group of cross-linked, light-induced, expandable, polymeric nanoparticles through miniemulsion polymerization. These synthesized nanoparticles were stable in aqueous solutions, although light irradiation led
血液输送过程中药物输送纳米载体的高稳定性对于有效的药物输送和低系统毒性至关重要,尽管这些纳米载体到达目标部位后需要有效释放才能稳定。为了开发有效的聚合物纳米载体,我们打算通过细乳液聚合合成和表征一组交联的,光诱导的,可膨胀的聚合物纳米颗粒。这些合成的纳米粒子在水溶液中是稳定的,尽管光照射导致粒子解开并进一步使粒子膨胀至体积的315倍。这导致在水溶液和三种细胞系(HeLa,RAW264.7和MCF-7)中有效释放封装的内容物。选择性触发释放也已成功实现了细胞单层的空间分辨率。此外,姜黄素的封装和释放的光调节得以实现。通过光激活成功地实现了封装的姜黄素的其他细胞活力。
