Recent progress in gene-sensing strategies for rapid detection of foodborne pathogens
Date:6/20/2013

the platforms of electrochemiluminescence (ECL) and microfluidic. Among these researches, the in situ ECL detection system is a representative work, to realize rapid, specific, yet highly sensitive foodborne pathogenic microorganisms genome test. The key idea of the novel system is integrating the in situ nucleic acids amplification using nano-magnetic primers and in situ ECL readout on magnetic beads based detection platform. They used Listeria monocytogenes as the target to examine the proposed technology, reaching a detection limit of fg/μL genome in 1 hour. The novel method has provided the evidence as a proof-of-concept, thus having potential for development of automatic mode for detection of the real samples.
