Development of fluorescent probes targeting the cell wall of pathogenic bacteria.

• Fluorescent Probes for the cell walls of pathogenic bacteria have been reviewed. • The function of the bacterial cell wall was discussed. • The composition and dynamic behavior of bacterial cell walls are discussed. • The cell wall components are used to classify the recognized objects. Contamination of pathogenic bacteria seriously threatens human health and safety, and the types and pathogenicity of bacteria are closely related to cell walls. Fluorescent probes can perform specific and sensitive detection of bacterial cells, and make an important contribution to the diagnosis of bacterial diseases and the development of antibiotics. In this review, we summarized the latest developments in integrating identification elements targeting bacterial cell walls with different chromogenic elements (small molecule fluorophores, conjugated polymers, and fluorescent nanomaterials) to detect and sense pathogenic bacteria. We hope this review paper can provide ideas for the design of new pathogen detection probes with better performance. [ABSTRACT FROM AUTHOR]
