Real-time PCR melting analysis with fiber optic SPR enables multiplex DNA identification of bacteria
2016
A fiber optic surface plasmon resonance (FO-SPR) technology was developed that enables simultaneous quantification and identification of multiple DNA targets on the same platform. The bioassay was based on the hybridization/melting of DNA-coated Au nanoparticles on the FO-SPR sensor when targets are present. The multiplex concept was successfully demonstrated on two related bacteria and for detection of multiple mutations in sequences. In conclusion, FO-SPR technology shows a great potential as a next generation in vitro diagnostics tool.
