单核细胞增生李斯特氏菌普遍存在于自然界中,是一种常见食源性致病菌,属于人畜共患病,可引起严重的李斯特氏菌病。因此,对食品中单增李斯特氏菌的控制和监测极为重要,以便更好地预防食源性疾病的暴发。目前,检测单增李斯特氏菌的方法中应用较为广泛的是传统的分离鉴定、分子生物学检测和免疫学检测法。传统方法易于操作、灵敏度高、成本低,但检测周期长,没办法满足对目的食物快速检测的需求。免疫学检测方法时间短,步骤简单,但该方法要依赖较高特异性的抗体。分子学检测法快速准确,灵敏度高,但是该方法需要有丰富的操作经验,而且需要特殊仪器。论文综述了传统方法、免疫学检测技术、分子生物学检测技术等多种单增李斯特氏菌的检测方法,结合最新参考文献就检测研究进展予以分析,以期为食品中单增李斯特氏菌的快速检测研究提供参考。

1 Introduction Identity privacy concerns hinder data sharing by casting doubt on the safeguarding of personal information,eroding trust,and impeding the willingness of individuals and organizations to exchange their data[1,2].The traceable ring signatures(TRSs)addresses the contradiction between identity privacy and regulation[3],no scheme has been developed thus far that is based on SM2,the Chinese cryptographic public key algorithm standard,without relying on centralized trust.

The convenient synthesis of the composite electrode with high supercapacitance performance plays an important role in practical application but is ***, the carbon nanotubes（CNTs） coupled with lowcrystalline sulfur and nitrogen co-doped Ni Co-LDH（denoted as SN-Ni Co-LDH） nanosheets array are grown on Ni Co foam（NCF） substrate by two convenient steps of metal induced self-assembly and corrosion engineering,which present the advantages of operating at roomtemperature and low preparation costs. Benefiting from the S–N co-doping and low-crystallinity of Ni Co-LDH, the prepared SN-Ni Co-LDH@CNTs@NCF electrode presents a topping charge capacity of 2470 C·g-1(4.94 C·cm-2) at 5 m A·cm-2. Furthermore, the fabricated asymmetry supercapacitor（ASC） achieves an extraordinary energy density of 77 Wh·kg-1(0.617 m Wh·cm-2) at a power density of 438 W·kg-1(3.5 m W·cm-2) and outstanding stability(91% capacity retention after 5000 cycles at20 m A·cm-2). Impressively, the structure evolution of Ni Co-LDH during the charge/discharge processes has been thoroughly elucidated by in-situ Raman spectra. Therefore,this work verifies a powerful strategy and practical value for preparing composite electrodes with high supercapacitance performance, and also provides guidance for the rational design of the smart electrodes.
