ABSTRACT Metal‐enhanced fluorescence (MEF) represents a captivating phenomenon that transpires when fluorophores are situated in close vicinity to the surface of metallic nanostructures, leading nuanced augmentation their fluorescent characteristics. Given its efficacy enhancing excitation rates, quantum yield, and photostability, MEF has firmly established itself as highly valuable tool for augmenting biosensor sensitivity, bioimaging clarity, intensifying therapeutic responses. Notably, plasmonic gold inherently advantageous MEF, have been widely utilized signal amplification, labeling, theranostics. In this endeavor, we undertake comprehensive examination MEF‐enabled meticulously analyzing fundamental enhancement mechanisms, crucial influencing factors, diverse modes enhancement. Furthermore, spotlight exemplary applications these nanostructures biosensing, bioimaging, theranostics, underscoring revolutionary potential. Ultimately, offer glimpse into future prospects improvement challenges beset gold‐based MEF. Our attention is steadfastly directed toward essential scientific questions technical hurdles remain be surmounted, inviting readers partake an exciting exploration dynamic promising field.

The conventional gold nanoparticles (AuNPs) with insufficient brightness face substantial challenges in developing a sensitive lateral flow immunoassay (LFIA). Herein, multibranched manganese–gold (Mn–Au) (MnAuNPs) Au core–Mn shell nanostructure were synthesized by one-pot method. Mn of valence-rich and core high electron transfer efficiency endowed MnAuNPs oxidase-like activity, which oxidized 3,3′,5,5′-tetramethylbenzidine (TMB) only transfer. Ox-TMB, was the oxidation product TMB, is an excellent photothermal agent. Furthermore, synergistic effect ox-TMB significantly enhanced conversion efficiency. has enabled highly quantitative detection. LFIA based on (cascade LFIA) achieved detection Escherichia coli O157:H7. entire process completed 25 min. limit cascade 239 CFU mL–1, 37.21-fold lower than that AuNPs-LFIA (8892 mL–1). recoveries 82.63–111.67%, coefficients variation 4.28–14.19%. Overall, this work suggests potential development broadens biosensing strategies for point-of-care testing.
