Abstract

Given the potential of Carbon Dots and their wide applications, strategies for their immobilization are vital for the development of specific, stable and sensitive (bio)chemical analysis. In this review we start by demonstrating the most common and efficient immobilization procedures used in Cdots. Subsequently, we describe the Carbon dots-host nanocomposites synthesis, properties, and ultimately outline and revise the fields where they have been used by presenting applications in this field. The Carbon dots-host nanocomposites enhanced properties are also explored, namely: increase photoluminescence intensity and electron transfer rates, induce light absorption, bandgap tuning, abundant introduction of functional groups, lower toxicity and biocompatibility.

碳点固定的挑战-综述

鉴于碳点的潜力及其广泛的应用，其固定化策略对于开发特异性、稳定性和敏感性（生物）化学分析至关重要。在这篇综述中，我们首先展示了用于Cdots的最常见和最有效的固定方法。随后，我们描述了碳点-宿主纳米复合材料的合成、性能，并最终概述和修订了它们在该领域的应用。研究了碳点-主体纳米复合材料的增强性能，即：增加光致发光强度和电子转移速率，诱导光吸收，带隙调谐，大量引入官能团，降低毒性和生物相容性。

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.
