A dual-mode lateral flow immunoassay based on DTTC-functionalized sea urchin-like gold nanoprobes for reliable detection of progesterone residues.
Progesterone (P4) is an important steroid hormone involved in mammalian reproductive regulation, and its accurate detection in animal-derived biological samples and foods is essential for reproductive status assessment and food safety monitoring. Herein, a colorimetric-photothermal dual-mode lateral flow immunoassay (L...
