尿酸是嘌呤在人体内代谢的最终产物，如果人们长期食用嘌呤含量高的食物或者不新鲜的各种肉类，使人体尿酸失衡，就容易导致血液中尿酸过高，引发一系列健康问题。本实验制备了一种新型Cd₂In₂S₅纳米晶，将Cd₂In₂S₅纳米晶与丝网印刷碳柔性电极结合，所得电极可用于尿酸检测。可通过检测尿酸含量来监测人体健康状况以及判断肉类新鲜程度。本实验创新性的将神奇的纳米材料走向市场，让中小学生、大学生、社会人群都能明白尿酸检测原理。实验所用材料便宜易得，操作简单，可实现尿酸的居家检测。

课程思政的有效融入是教学质量提升和高素质人才培养的关键。我们以“电动势法测定化学反应的热力学函数”这一实验项目为例，构建了一次深入的实验探究与思政教育相结合的教学实践活动。通过对电动势测定原理和方法的探讨以及反应热力学量的导出，学生们不仅深化了对相关基础理论知识的理解，提升了他们解决实际问题的实验技能和创新能力;同时强化了学生的家国情怀以及责任担当意识。

Metal-organic framework (MOF) MIL-101 and surface plasmon polariton (SPP) supported gold nanoparticles (Au NPs) hybrid systems were developed as a highly sensitive and reproducible surface-enhanced Raman scattering (SERS) detection platform, in which a green electrostatic self-assembly technology was adopted to construct the substrate. In an aqueous solution, the electronegativity of the particles can be used to prepare the composite substrate without any surface modifier. Due to the enrichment capacity of MIL-101 and the electromagnetic enhancement from Au NPs, the well-designed MIL-101/Au composites possessed ultrahigh sensitivity with the detection limit of Rhodamine 6G (R6G) as low as 10^-10 mol·L^-1. Meanwhile, the substrate exhibits high stability, excellent reproducibility, and recyclability. Additionally, the novel substrate can be explored for direct capture, and sensitively detect pesticide residues such as thiram.
