AbstractThe authors report on the preparation of composites made from graphene oxide (GO) and zeolitic imidazolate framework-8 (ZIF-GO), with various fractions of GO. GO acts as the template and as a modulator for the surface properties of the composites. It also improves the selective adsorption of specific proteins, i.e. hemoglobin (Hb) in this case. The adsorption capacity for Hb is as high as 436 mg g−1 when using a composite containing 20% of GO as sorbent, and 95% of specific activity is maintained for the Hb recovered. The sorbent is applied to selectively isolate Hb from human whole blood. Graphical abstractGraphene oxide-zeolitic imidazolate framework-8 composites (ZIF-GO) with varying mass ratios of GO were prepared in order to tune surface properties and to improve the adsorption selectivity toward hemoglobin.

由氧化石墨烯和沸石咪唑酯骨架 8 制备的可调谐复合材料，用于改善血红蛋白的选择性分离

摘要作者报告了由氧化石墨烯 (GO) 和沸石咪唑酯骨架 8 (ZIF-GO) 制成的复合材料的制备，以及不同比例的 GO。GO 作为模板和复合材料表面特性的调节剂。在这种情况下，它还可以改善特定蛋白质（即血红蛋白 (Hb)）的选择性吸附。当使用含有 20% GO 的复合材料作为吸附剂时，Hb 的吸附容量高达 436 mg g-1，并且对回收的 Hb 保持了 95% 的比活性。该吸附剂用于从人全血中选择性分离 Hb。为了调整表面性质并提高对血红蛋白的吸附选择性，制备了具有不同 GO 质量比的氧化石墨烯-沸石咪唑酯骨架 8 复合材料（ZIF-GO）。
