A review on advances in DNA-intercalators for sensor technologies: Mechanisms, applications, and innovations

Background

DNA intercalators have attracted considerable attention in the field of sensor technology due to their unique ability to insert between base pairs of nucleic acids, resulting in measurable optical or electrochemical changes. Recent advancements in molecular biology, nanotechnology, and optoelectronic sensing have expanded the applications of DNA intercalators beyond anticancer drug development to include biosensing and environmental monitoring. They enable highly sensitive and specific detection of target molecules through fluorescence, colorimetric, and electrochemical signal transduction. However, comprehensive reviews on their role in sensing remain limited. This review summarizes their classification, mechanisms, recent biosensing applications, and future research directions.

Results

DNA-intercalators, a class of molecules capable of inserting between and specifically binding to DNA double-helix base pairs, have attracted attention for their wide range of applications in molecular biology, drug discovery, and detection technologies. This paper reviews the origin and mechanisms of action of DNA intercalators, with a particular focus on their classification and recent advances in analytical and biomedical applications. DNA-intercalators have shown significant value in sensor development, especially in heavy metal ion detection, specific nucleic acid sequence recognition, and drug screening through fluorescence, colorimetric, and electrochemical signal transduction. Finally, the article summarizes the limitations of current research and looks forward to the development of novel low-toxicity insertion agents and multi-target detection platforms.

Significance

This review is significant for promoting the development of DNA-intercalators and provide a reference for the research and application of DNA-intercalators.

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
