生物相容的pH响应性溶胶 - 凝胶纳米传感器可并入聚(乳酸 - 共 - 乙醇酸)(PLGA)电纺支架。所产生的自我报告的支架可用于在微环境条件原位监测,同时在所述支架中培养细胞。这是有益的,因为在三维细胞构建体可以在实时而不干扰试验来监测。
以下实验的总体目标是生产 pH 响应纳米传感器和自我报告支架,这些支架可以实时和原位监测,以帮助了解影响细胞生长的条件。这是通过首先制备生物相容性分析物响应纳米传感器来实现的,该传感器可以通过荧光输出监测 pH 值。作为第二步,将 pH 响应纳米传感器整合到聚合物电纺支架中,形成一个 3D 环境,可以在该环境中培养和监测细胞。
接下来,哺乳动物细胞位于电旋转支架上,纳米传感器也被输送到其细胞内环境中,以监测细胞内的 pH 值。在实验过程中,获得的结果表明,细胞内纳米传感器和自我报告支架能够根据共聚焦显微镜获得的荧光比率监测组织工程环境中的 pH 值。与现有方法(例如使用电子 pH 探头)相比,该技术的主要优点是可以原位实时进行测量,而不必干扰细胞生长。
