Wavelength-dependent absorbance of blood has impeded the development of fluorescence biodetection in whole blood. Here, by replacing the fluorescence working signal with a temperature signal, reliable H₂S detection was performed in samples of whole blood. The developed system was based on a dual-channel lanthanide-doped nanoprobe, which further allowed precise serodiagnosis of acute pancreatitis.
