Surface plasmon resonance (SPR) is a medical diagnosis technique with high sensitivity and specificity. In this research, a new method based on SPR is proposed for rapid, 10-minute detection of the anti-dengue virus in human serum samples. This novel technique, known as rapid immunoglobulin M (IgM)-based dengue diagnostic test, can be utilized quickly and easily at the point of care. Four dengue virus serotypes were used as ligands on a biochip. According to the results, a serum volume of only 1 μl from a dengue patient (as a minimized volume) is required to indicate SPR angle variation to determine the ratio of each dengue serotype in samples with 83-93% sensitivity and 100% specificity.
表面等离子体共振（SPR）是一种具有高灵敏度和特异性的医学诊断技术。在本研究中，提出了一种基于SPR的新方法，用于在10分钟内快速检测人血清样本中的抗登革病毒。这种新技术，即基于快速免疫球蛋白M（IgM）的登革热诊断测试，可在护理点快速简便地使用。四种登革病毒血清型被用作生物芯片上的配体。根据结果，仅需1微升登革热患者的血清（作为最小化体积）即可指示SPR角度变化，以确定样本中每种登革热血清型的比例，灵敏度为83%-93%，特异性为100%。
