Abstract:
Easy detection: The target DNA in a 10-100 aM range can be detected by pre-complexed nanoparticles without additional amplification or target labeling. The [Ru(bpy)(3)](2+)-doped silica nanoparticles are hybridized to form a complex with highly enhanced sensitivity (see scheme). This method will be a significant improvement over conventional microarray/fluorescence readout systems.
