The detection of glucose is important in clinic diagnosis, while the traditional methods for glucose sensing rely heavily on glucose oxidase (GOx). Herein, with the easy preparation, stability as well as selectivity, a polyvinyl borate (PVB) hydrogel was used for the non-GOx and portable detection of glucose. In the colorimetric channel, the hydrogel can be specifically decomposed in the presence of glucose, thus the electric resistance can be changed, causing significant color change of the electrochromic Prussian blue (PB) film in a very short time of 3 s. A linear relationship between the grayscale value of PB and glucose concentration was established in the range between 0.1 and 10.0 mM with the limit of detection (LOD) of 0.02 mM. In addition, the alkaline phosphatase (ALP) in the PVB gel was released to react with L-ascorbyl-2-phosphate, thus the product of ascorbic acid can reduce HAuCl₄ to form the aggregation-induced emission enhancement (AIEE) of Au nanoclusters. Two separate ranges with glucose concentrations of 0.1–1.0 mM and 1.0–10.0 mM, and also a LOD of 0.018 mM were achieved. In particular, a mobile APP was designed to read the grayscale values of PB, making the sensor suitable for the on-site detection. Overall, this work may show a great potential in low-cost, stable and portable glucose detection.

葡萄糖的检测在临床诊断中很重要，而传统的葡萄糖传感方法严重依赖葡萄糖氧化酶（GOx）。在此，聚乙烯硼酸 (PVB) 水凝胶具有制备简单、稳定性和选择性好等优点，用于非 GOx 和便携式葡萄糖检测。在比色通道中，水凝胶可以在葡萄糖存在的情况下特异性分解，从而改变电阻，在极短的3 s时间内引起电致变色普鲁士蓝（PB）膜的显着颜色变化。PB 的灰度值与葡萄糖浓度之间的线性关系建立在 0.1 和 10.0 mM 之间，检测限 (LOD) 为 0.02 mM。此外，PVB凝胶中的碱性磷酸酶（ALP）被释放出来与L反应。-ascorbyl-2-磷酸盐，因此抗坏血酸的产物可以还原HAuCl ₄以形成Au纳米团簇的聚集诱导发射增强(AIEE)。葡萄糖浓度为 0.1-1.0 mM 和 1.0-10.0 mM 的两个不同范围，以及 0.018 mM 的 LOD。特别是设计了一个手机APP来读取PB的灰度值，使传感器适合现场检测。总体而言，这项工作可能在低成本、稳定和便携式葡萄糖检测方面显示出巨大的潜力。
