Abstract:
A carbon nanotube (CNT)-based multiple cycle signal amplification strategy has been demonstrated for detection of single-digit foodborne pathogens with the naked eye. In the present design, CNTs are used as carriers for loading numerous horseradish peroxidase (HRP) and concanavalin A (ConA) tags, and multiple cycle signal amplification is achieved through the biotinylated anti-HRP antibody and avidin-HRP.
