Integrating surface-enhanced fluorescence (SEF) and surface-enhanced Raman spectroscopy (SERS) into a single probe is a natural step forward for plasmon-enhanced spectroscopy (PES), as SEF enables enhanced fluorescent imaging for fast screening of targets, while SERS allows ultrasensitive trace molecular characterization with specificity. However, many challenges remain, e.g.

Antibiotic-resistant superbugs are a global threat that are predicted to become the leading cause of death worldwide. To effectively combat superbugs, accurate prediction of antibiotic susceptibility is crucial, which takes more than 24 h in clinics now. Herein, we report doxycycline (DX) antibiotic-decorated silver nanoparticle (AgNP)-based plasmonic metal-enhanced fluorescence (PMEF) nanoplatforms for accurate, rapid, and sensitive prediction of antibiotic susceptibility against different superbugs.

Tricresyl phosphate (TCP), a typical aryl-organophosphorus flame retardant, has been shown to exhibit neurotoxicity, genotoxicity, and reproductive and developmental toxicity. The release of TCP into the environment through human activities has raised significant global concerns, creating a demand for efficient, rapid, and portable TCP detection methods. In this study, a fluorescence turn-on sensor based on NU-1000 was developed for the selective detection of TCP.

Conventional bow-tie or dimer gap plasmons with C-symmetry are highly polarization dependent, which is unforvable in practice for unpolarized incident light sources and randomly dispersed fluorescence emitters. A nanocross configuration with C-symmetry could yield polarization-independent fluorescence enhancement, but the severe proximity effect during the nanofabrication process limits the gap size and the ultimate fluorescence enhancement. In this study, an advanced fabrication protocol is developed based on the concentric contour exposure strategy to overcome the notorious proximity effect, realizing a densely packed nanocross array with small gaps that is beyond the limit of conventional area exposure method.
