Cardiovascular diseases (CVDs) are the leading causes of death worldwide.
An easy-to-use, low-cost and portable fluorescent lateral flow immunoassay based on paper microfluidics was developed for the point-of-care diagnosis of non-communicable diseases.
A novel spatial-resolved electrochemiluminescent (ECL) ratiometry for cardiac troponin I (cTnI) analysis was developed using resonance energy transfer (RET) and a coreactant consumption strategy for signal amplification.
Herein, we have reported a new one-step potentiometric immunoassay for the sensitive and specific detection of human plasma cardiac troponin I (cTnI), a biomarker of cardio-cerebrovascular diseases.
