摘要

We have designed a microfluidic device that is capable of enhancing passive mixing through the micro-structures, positioned along the channels of the device. We investigated the capability of these structures to promote mobile hybridization of fluorophore-labeled target oligonucleotides to Au-NP probes. This process is monitored with fluorescence through the quenching of the fluorescent signal within the device as the target oligonucleotides become bound to the Au-NP probes. We evaluated the fluorescent intensity of a sample image which was completed in about 7.2 s. Mobile hybridization is thus much more effective than traditional static hybridization limited by molecular diffusion.
