随后通过紫外分光光度计检测各载药体系载药率和包封率,最终选择载药率最高的DFO 7.5@ZIF-8用于后续表征。TEM Mapping显示DFO 7.5@ZIF-8纳米粒子中含有DFO特征性的S元素;Zn2+及DFO的释放动力学表明,ZIF-8载体在前24h崩解速度最...
同时,Fe/Mn-ZIF-8壳层的降解使这种纳米粒子具有体内增强的近红外二区成像功能,为光动力和化学动力学治疗过程提供了精确的引导。 Figure 1. TEM images of the NaErF4:Tm (a), LDNPs (b), LDNPs-PVP (c) and LDNPs@Fe/Mn-...
我们通过快速电流驱动法(FCDS)1 h内在多孔PP基底上合成了厚度在1 µm以内的ZIF-8层(Figure 1)。 ▲Figure 1. (a) Schematic illustration of the ZIF-8 membranes prepared on brittleinorganic substrate and flexible polymer substrate.Top-view (b) andcross-sectional (c) SEM images of the bare PP ...

Its morphology and structure were fully characterized by high-resolution transmission electron microscopy, X-ray diffraction, transmission electron microscopy element mapping, and X-ray photoelectron spectroscopy. Additionally, its oxidase-like activity was explored with Km of 0.21 mM and Vmax of 1.74 ×...
