Plasmon-Enhanced Fluorescence Lateral Flow Assay Using Silica-Spaced Ag@SiO2@RuBpy Nanoprobes for Ultrasensitive and Dual-Mode Procalcitonin Detection
Ultrasensitive and quantitative detection of procalcitonin is crucial for the early diagnosis of bacterial sepsis, yet conventional gold-nanoparticle-based lateral flow assays (AuNP-LFAs) are often limited by insufficient sensitivity. Herein, we report a dual-mode colorimetric-fluorescence LFA platform employing Ag@S...
