Living-cell imaging demands high specificity,sensitivity,and minimal background interference to the targets of interest.However,developing a desirable imaging probe that can possess all the above features is still challenging.The bioorthogonal surface-enhanced Raman scattering (SERS) imaging has been recently emerged through utilizing Raman reporters with characteristic peaks in Raman-silent region of cells (1800-2800 cm-1),which opens a revolutionary avenue for living-cell imaging with multiplexing capability.In this review,we focus on the recent advances in the technology development and the biological and biomedical applications of the living-cell bioorthogonal SERS imaging technique.After introduction of fundamental principles for bioorthogonal tag or label,we present applications for visualization of various intracellular components and environment including proteins,nucleic acids,lipids,pH and hypoxia,even for cancer diagnosis in tissue samples.Then,various bioorthogonal SERS imaging-guided therapy strategies have been discussed such as phototherapy and surgery.In conclusion,this strategy has great potential to be a flexible and robust tool for visualization detection and diseases diagnosis.

以江苏省丰县为例,采用核密度、标准差椭圆等方法,探讨19902018年淮海经济区县域制造业结构演替时空异质性特征.淮海经济区县域制造业的行业结构呈现由资源劳动密集型向技术密集型演变,民营企业主导所有制结构演替,呈现大中型企业规模优势渐显、小型企业主体地位持续下降的趋势.研究期内县域优势主导产业快速演替,但近年来产业结构演替缓慢,发展后劲不足.丰县制造业分布呈现由以县城为中心的核心边缘格局,逐步演化为以县城为核心、以主要交通干线为依托、以重点镇为节点的“一核一轴多心”的空间格局.
