摘要

The precise identification and detection of circulating tumor cells (CTCs) is significant for the early diagnosis and prognostic treatment of cancer. However, it remains a challenge to detect CTCs with high sensitivity and specificity. In this study, a colorimetric sensor for the analysis of CTCs was constructed based on dual-aptamer recognition and core (Fe3O4)–shell (Pt) nanoparticle (Fe3O4@Pt NP) nanozymes coupled with a G-quadruplex as a signal transducer/amplifier. The results show that the linear range of the designed colorimetric sensor is 50–4000 cells and the detection limit is 4 cells. The constructed aptasensor could be extended to identify various CTCs by changing the aptamers, and holds great potential in precise tumor diagnosis.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
