Abstract

Diabetes is a serious disease with a huge number of patients worldwide. Glucose levels in people with diabetes are above 6.6 mM in blood samples and 200 μM in saliva samples. Metal-organic frameworks (MOFs) have outstanding properties for glucose sensors, such as a large surface area and being rich in active sites. In this research, a silver nanoparticle@Ni-BTC (AgNP@Ni-BTC) composite was synthesized through one-pot synthesis using a microwave at 130 °C for 1 hour at 200 W. The results showed that the 4%AgNP@Ni-BTC-modified carbon paste electrode obtained better sensor performance than Ni-BTC with a limit of detection (LoD) of 14.73 μM, a sensitivity of 6584.89 μA mM⁻¹ cm⁻², and a linear range of 10–1250 μM. The 4%AgNP@Ni-BTC-modified carbon paste electrode also had better stability than Ni-BTC and had good reproducibility. Glucose detection tests on salivary samples showed that the 4%AgNP@Ni-BTC-modified carbon paste electrode could be used to measure glucose levels in salivary samples.

一锅微波辅助合成棒状和六边形板状AgNP@Ni-BTC复合材料的潜在唾液葡萄糖传感器

糖尿病是一种严重的疾病，全世界有大量的患者。糖尿病患者的血液和唾液中的葡萄糖浓度分别超过6.6 μM和200 μM。金属有机骨架(mof)具有表面积大、活性位点丰富等优点。本研究以银nanoparticle@Ni-BTC (AgNP@Ni-BTC)复合材料为研究对象，在200 W下，在130°C微波条件下，一锅合成1小时。结果表明，4%AgNP@Ni-BTC-modified碳糊电极的传感器性能优于Ni-BTC，检测限为14.73 μM，灵敏度为6584.89 μA mM−1 cm−2，线性范围为10 ~ 1250 μM。4%AgNP@Ni-BTC-modified碳糊电极也比Ni-BTC具有更好的稳定性和良好的重现性。唾液样品葡萄糖检测试验表明，4%AgNP@Ni-BTC-modified碳糊电极可用于唾液样品葡萄糖水平的测量。
