Summary: In clinical work, early diagnosis of subarachnoid hemorrhage (SAH) is primarily based on conventional imaging techniques and neurological assessments. However, the association between imaging manifestations and clinical findings is imperfect, especially in SAH patients with a lower amount of blood. The development of a direct, rapid, and ultra-sensitive detection method based on electrochemical biosensors has emerged as a new competitive challenge in SAH biomarkers research.

Summary: An electrochemiluminescence resonance energy transfer (ECL-RET) immunosensor was constructed to detect beta-2-microglobulin (B2M) by using carbon nitride nanosheet and nickel- and iron-based organic framework modified with gold nanoparticles. The sandwich immunosensor showed a decrease in ECL intensity with increasing B2M concentration due to low conductivity of B2M. The ECL-RET immunosensor had a linear range of 10 fg/mL to 10 ng/mL and a limit of detection of 2.3 fg/mL (S/N = 3), exhibiting high sensitivity, specificity, and stability for B2M detection.
