A dual-aptamer-based, dual-mode FRET lateral flow strip is developed for the rapid and sensitive detection of thrombin in serum samples, achieving a fluorescence-based detection limit of 0.135 nM-twice as sensitive as the colorimetric method.
A dual-mode colorimetric–photothermal LFIA platform was successfully constructed for the detection of thrombosis-related biomarkers, including thrombomodulin and α2-plasmin inhibitor–plasmin complex, in clinical serum samples, enhancing analytical sensitivity and reliability.
