A graphene foam/zirconium-based metal–organic framework composite (GF/UiO-66) was synthesised and then employed to modify glassy carbon electrodes (GCE). These modified electrodes were successfully used for the simultaneous detection and determination of acetaminophen (AC) and tryptophan (TRYP). The combination of GF and UiO-66 endowed the electrodes with a large surface area, good biological compatibility and stability as well as high selectivity and sensitivity. The linear calibration plots for AC and TRYP were obtained over the range of 0.5–200 μM (R2 = 0.999) and 0.5–113 μM (R2 = 0.999) with detection limits of 0.07 μM and 0.06 μM, respectively. The modified electrodes were successfully applied for the determination of AC and TRYP in a pharmaceutical preparation and urine, respectively.

使用复合石墨烯泡沫/ Zr-MOF膜修饰电极同时定量对乙酰氨基酚和色氨酸
合成了石墨烯泡沫/锆基金属-有机骨架复合材料（GF / UiO-66），然后将其用于修饰玻璃碳电极（GCE）。这些修饰电极已成功用于对乙酰氨基酚（AC）和色氨酸（TRYP）的同时检测和测定。GF和UiO-66的结合使电极具有较大的表面积，良好的生物相容性和稳定性以及高选择性和灵敏度。AC和TRYP的线性校准图在0.5–200μM（R 2 = 0.999）和0.5–113μM（R 2= 0.999），检出限分别为0.07μM和0.06μM。修饰的电极分别成功地用于药物制剂和尿液中AC和TRYP的测定。
