제목 Post-probe attached hydrogel microparticle for multiplexed miRNA detection
초록 Recently, encoded hydrogel particles have gained much attention as these particles enable high performance multiplexed miRNA assays. However, due to the low conversion of hydrogel microparticle synthesis step, current microparticles can incorporate only about ~10% of input ssDNA probes. Here, we presented a novel post-probe attached hydrogel microparticles to overcame the limitation of current particles. By discovering that the hydrogel microparticles contain the unconverted, yet reactive double bonds inside the network, we covalently anchored the ssDNA probes after the particle synthesis. With this method, probe density increased about 8.2 times compared to that of conventional particles. We demonstrated that the increased probe density leads to better assay capability. We also demonstrate a potential application of post-probe attached hydrogel microparticles by conducting multiplexed miRNA detection in human plasma samples.
