摘要

金属配合物及其复合材料最近成为比色分析的关键元素，推动了传感器技术的实质性进展。由于其优越的光学特性，金属配合物比色传感器非常适合于检测各种分析物。这些复合材料的传感特性可以通过改变金属中心（过渡金属、镧系元素或主族金属离子）来适应特定的分析物。与金属配合物相比，金属配合物基复合材料在比色传感方面具有更高的灵敏度和稳定性，这主要是因为金属配合物与各种纳米材料（包括金属、金属氧化物和碳基材料）的协同集成。尽管这一领域取得了长足的进展，但金属配合物的结构设计及其复合材料的制备和性能调控仍然具有挑战性。本文从金属中心、复合纳米材料、比色机理和应用等方面综述了近十年来金属配合物比色传感器的研究进展，指出了金属配合物及其复合材料比色传感技术的发展和应用前景。

Advances in metal complex-based colorimetric sensors

Metal complexes and their composites have recently emerged as the pivotal elements of colorimetric analysis, driving substantial progress in sensor technology. Owing to their advantageous optical properties, metal complex-based colorimetric sensors are well suited for detecting various analytes. The sensing properties of these composites can be tailored to specific analytes by varying the metal center (transition metal, lanthanide, or main-group metal ion). Compared with metal complexes, metal complex-based composites achieve markedly higher sensitivities and stabilities in colorimetric sensing, primarily because of the synergistic integration of metal complexes with diverse nanomaterials, including metals, metal oxides, and carbon-based materials. Despite the considerable progress in this field, the structural design of metal complexes and the preparation and performance regulation of their composites remain challenging. Herein, we review the metal complex-based colorimetric sensors developed in the past decade from the perspectives of metal centers, composite nanomaterials, colorimetric mechanisms, and applications, highlighting the need for further research to foster the advancement and utilization of colorimetric sensing based on metal complexes and their composites.

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.
