摘要
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. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
