源起于发霉甜苜蓿，脱胎于生化实验室，华法林先生起初作为一种强力灭鼠毒药大杀四方。然而，在进入医药领域的道路上，他却因毒药的身份标签和种种流言而饱受质疑和反对。科学家们揭示了华法林抗凝血的机制，并证明了华法林抗凝治疗对患者的益处。从此，华法林先生以及他的衍生物们成为了抗凝治疗和防治鼠害的前线战士。

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。

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.
