中文摘要:
      目的 介绍荧光银纳米簇(AgNCs)的合成方法、荧光特性、抗菌活性,及其在食品包装中的应用。方法 总结国内外AgNCs在食品包装检测领域的应用,以及其作为新型抗菌材料体现出的强大抗菌效力,提出AgNCs的不足之处和可能的解决方法。结论 AgNCs由于其光漂白性低、荧光量子产率高、经济效益好,可作为荧光材料设计生物传感器用于检测食品包装内的污染物。此类生物传感器具有检测快速、灵敏与特异性识别的优点。同时AgNCs具有大的表面积与体积比,高的局部表面Ag浓度、高迁移率及低毒性等特点,使其抗菌性能优于传统的银纳米材料,由此,展望了新型抗菌检测双重功效AgNCs传感器的设计。
英文摘要:
      The work aims to introduce the synthesis methods, fluorescence characteristics, antibacterial activity of fluorescent silver nanoclusters (AgNCs) and their applications in food packaging. The application of domestic and overseas AgNCs in the field of food packaging detection and the strong antibacterial efficacy of AgNCs as a new type of antibacterial material were summarized. The inadequacies and possible solutions of AgNCs were proposed. Due to its low photo bleaching, high fluorescence quantum yield and good economic efficiency, AgNCs can be used as a fluorescent material to design biosensors to detect contaminants in food packaging. These biosensors are featured by rapid detection, sensitive identification and specific recognition. At the same time, the advantages of large surface area to volume ratio of AgNCs, high local surface Ag concentration, high mobility and low toxicity make its antibacterial performance superior to traditional silver nanomaterials. Therefore, the design of a new dual-function AgNCs sensor for both anti-bacteria and detection is envisioned.
