肿瘤细胞成像在肿瘤早期诊断、治疗监测及预后评估中具有关键价值。然而,传统成像技术灵敏度和特异性不足,难以在复杂的肿瘤微环境中分辨出低丰度的生物标志物。DNA逻辑电路凭借其可精准编程、分子识别特异性强及信号放大能力突出等优势,成为肿瘤细胞成像领域的研究热点,其能够通过构建复杂的分子逻辑网络实现对肿瘤标志物的智能响应,但其在体内成像中的稳定性、递送效率以及与临床检测兼容性等方面仍存在诸多待解决问题。本文综述了酶驱动和熵驱动DNA逻辑电路在肿瘤细胞成像中的构建原理、技术策略及应用进展,旨在系统梳理其发展现状,剖析现存瓶颈,为推动DNA逻辑电路在肿瘤细胞成像领域的临床转化提供理论参考。
Tumor cell imaging has key value in early tumor diagnosis,treatment monitoring,and prognosis evaluation. Conventional cell imaging techniques lack sufficient sensitivity and specificity to identify low-abundance biomarkers in the complex tumor microenvironment. DNA logic circuits have become a research hotspot in tumor cell imaging due to their advantages of precise programming,strong specificity in molecular recognition,and outstanding signal amplification ability. They can realize intelligent responses to tumor marke
rs by constructing complex molecular logic networks. However,there are still many problems to be solved in terms of stability,delivery efficiency,and compatibility with clinical detection in
in vivo
imaging. This article reviews the construction principles,technical strategies,and application progress of enzyme-driven and entropy-driven DNA logic circuits in tumor cell imaging. It aims to systematically summarize the development of the technology,analyze the existing bottlenecks,and provide a theoretical reference for promoting the clinical transformation of DNA logic circuits in tumor cell imaging.
