PCR-free quantitative detection of genetically modified organism from raw materials. An electrochemiluminescence-based bio bar code method.


A bio bar code assay based on oligonucleotide-modified gold nanoparticles (Au-NPs) provides a PCR-free method for quantitative detection of nucleic acid targets. However, the current bio bar code assay requires lengthy experimental procedures including the preparation and release of bar code DNA probes from the target-nanoparticle complex and immobilization… (More)
