With increasing diabetes patients in the near future, development of non-enzymatic glucose biosensor is highly demanded due to their greater sensitivity and resistance to external stimuli compared to enzymatic biosensors. Zinc ferrite (ZnFe₂O₄, ZFO) nanoparticles (NPs) were fabricated using a simple solution combustion method together with freeze drying. The NPs have high crystallinity, large aspect ratios and narrow size distributions. Plenty of defects have been induced during lyophilisation and greatly improves the glucose biosensing performance during electrochemistry test. The freeze-dried ZFO NPs are highly crystalline and agglomeration-free, these assures the sample with high sensitivity, superior selectivity, low detection limit and outstanding stability for electrochemical glucose biosensing.

在不久的将来，随着糖尿病患者的增加，由于与酶促生物传感器相比，非酶促葡萄糖生物传感器具有更高的敏感性和对外部刺激的抵抗力，因此非常需要开发非酶促葡萄糖生物传感器。锌铁氧体（ZnFe ₂ O ₄, ZFO) 纳米粒子 (NPs) 是使用简单的溶液燃烧法和冷冻干燥法制备的。纳米颗粒具有高结晶度、大纵横比和窄尺寸分布。冻干过程中产生了大量缺陷，大大提高了电化学测试过程中的葡萄糖生物传感性能。冻干的 ZFO NPs 是高度结晶且无团聚的，这确保了样品具有高灵敏度、卓越的选择性、低检测限和电化学葡萄糖生物传感的出色稳定性。
