摘要
肿瘤筛查中通常采用多种肿瘤标志物的联合检测以提高诊断率。因此,为了提高筛查效率,亟需一种多元分析技术应用于肿瘤筛查。液相芯片技术是由基因微阵列生物芯片技术演变而来的多元分析技术。它由编码微球、探针分子、目标分子和报告分子四部分组成,可用于目标物的定量分析。微球编码技术是液相芯片技术的研究热点,本文中涉及的光子晶体编码是光学编码策略的一种,具有良好的稳定性和解码性能。长期研究表明,光子晶体编码液相芯片在肿瘤筛查、诊断中应用前景广阔。本文综述了光子晶体编码液相芯片技术的基本原理、技术特点及在肿瘤筛查中的应用现状。
Multiple tumor makers are needed to improve the diagnostic rate of the simultaneously detection of malignant tumors through screening. Therefore, multiplex detection technology is urgently required to improve the screening efficiency. Suspension arrays are multiplex detection method based on gene microarrays. It consists of encoded microbeads, probes, targets, and report molecules are applied to analyze targets quantitatively. The microbead encoding strategy is a hotspot in suspension array research. The photonic crystal encoding mentioned in this review is a type of optical encoding that is very stable and easily decoded. Photonic suspension arrays have broad prospects in the screening and diagnosis of malignant tumors through long-term studies. This review summarizes the basic principle, classification, and characteristics of photonic suspension arrays and their application in the screening of malignant tumors.
