Abstract

Cardiovascular and cerebrovascular diseases represent the leading causes of mortality among middle-aged and elderly populations in China, with inflammation identified as a significant contributing factor. Consequently, the early diagnosis and management of inflammation are of paramount importance. C-reactive protein (CRP) and procalcitonin (PCT) serve as biomarkers for myocardial inflammation. In this study, we developed a quantum dot immunochromatographic strip that was capable of simultaneously detecting these two biomarkers with enhanced sensitivity and specificity. The comb amphiphilic poly (octadecyl-alt-polyethylene glycol) was synthesized through an amide reaction, which was employed to coat oil-soluble quantum dots, thereby transforming them into water-soluble quantum dots microbeads suitable for the coupling with biological macromolecules. These quantum dots microbeads were utilized as luminescent materials in the immunochromatographic strip for the concurrent detection of CRP and PCT. The assay required only 100 μL of sample and provided results within 10 min, demonstrating commendable precision, stability, sensitivity, and accuracy. Clinical evaluations confirmed that the developed CRP and PCT quantum dots immunochromatographic test strips were accurate and reliable, underscoring their significant potential for practical routine clinical application in the early accurate diagnosis of myocardial inflammation.

制备具有高稳定性、更高灵敏度并可用于 C 反应蛋白 (CRP) 和降钙素原 (PCT) 免疫层析体外诊断试剂的核壳量子点微珠
在中国,心血管和脑血管疾病是中老年人群死亡的主要原因,而炎症被认为是其中一个重要因素。因此,炎症的早期诊断和管理至关重要。C反应蛋白(CRP)和降钙素原(PCT)是心肌炎症的生物标志物。在这项研究中,我们开发了一种量子点免疫层析条带,能够同时检测这两种生物标记物,并提高了灵敏度和特异性。我们通过酰胺反应合成了组合两亲性聚(十八烷基-醇-聚乙二醇),并用其包覆油溶性量子点,从而将其转化为适合与生物大分子偶联的水溶性量子点微珠。这些量子点微珠被用作免疫层析条带中的发光材料,用于同时检测 CRP 和 PCT。该检测方法只需 100 μL 样品,10 分钟内即可得出结果,其精确度、稳定性、灵敏度和准确性都值得称赞。临床评估证实,所开发的 CRP 和 PCT 量子点免疫层析试纸条准确可靠,在临床常规应用中具有巨大潜力,可用于早期准确诊断心肌炎症。
