中文摘要:荧光纳米生物传感平台由于具有灵敏度高、选择性好、操作简单、成本低、实时监测等特点,吸引了广泛的关注。近年来,随着纳米技术的飞速发展,具有纳米结构的材料(纳米材料)在生物传感领域显示出独特的优势。与传统材料相比,纳米材料显示出独特的物化性质,如光学、电学、机械、催化和磁性等。金属(如Au、Ag、Cu及其合金)纳米簇(MNCs)是纳米科学和纳米技术领域中一种新颖的多功能纳米材料,其通常由几个到几十个金属原子组成,其核的尺寸通常小于2 nm。由于其发光能力强、易于合成和进行表面功能化、生物相容性好、尺寸超小、毒性低等优点,金属纳米簇在能源催化、医学诊断、电子器件、生物传感等领域得到了广泛的应用。此外,金属纳米簇的荧光性能极佳(如大的斯托克斯位移、可调节的荧光、高的光学稳定性和荧光量子产率等),因此被作为荧光纳米探针广泛应用于生物传感领域。该综述介绍了近年来基于不同构建机制的金属纳米簇基的传感平台的研究进展,及其在检测离子、生物分子、pH和温度传感等方面的应用。相信该综述能为从不同传感机理构建更具前景的生物传感器提供一些新见解和理论指导。

Recent Advances in Metal Nanoclusters-based Fluorescent Platforms for Biosensing
Abstract:Biosensing platform is one of the branches of chemical sensing platform,which is sensitive to the biomolecules and can convert the concentration changes of biomolecules into electric signal for the sensing purpose.Among the various biosensing platforms,fluorescent nano-biosensing platforms have attracted widely attention due to their advantages of high sensitivity,good selectivity,operational simplicity,low cost,real-time monitoring,etc.In recent years,with the rapid development of nanotechnology,nanostructured materials(nanomaterials) exhibit some special advantages in the field of biosensing.Compared with the traditional materials,nanomaterials exhibit unique physical and chemical properties,such as optical,electrical,mechanical,catalytic and magnetic properties.As a novel type of multifunctional nanomaterials in nanoscience and nanotechnology,metal(e-g.,Au,Ag,Cu,and their alloys) nanoclusters(MNCs) are typically composed of several to dozens of metal atoms whose core sizes are usually below 2 nm.Benefiting from their unique properties of strong photoluminescence,facile preparation and surface functionalization,excellent biocompatibility,ultra-small size and low toxicity,MNCs have been applied in many fields such as energy catalysis,medical treatment,electronic devices and biosensing.Especially,they have extremely outstanding fluorescent properties of large Stokes shift,tunable fluorescence emission,high optical stability and fluorescence quantum yield,compared with the traditional fluorescent organic dyes,proteins,quantum dots and other fluorescent materials.Based on the above properties,MNCs have been widely used as fluorescent nanoprobes in the field of biosensing.In this review,the latest development of MNCs based fluorescent nano-biosensing platforms on the basis of various construction mechanisms were presented.The applications of MNCs in the field of sensing ions,biomolecules,pH and temperature were introduced.It is believed that this review could provide some novel insights and theoretical guidance to construct more prospective biosensors based on different designed sensing mechanisms.
