In this work, a novel mesoporous luminescence-functionalized metal-organic framework (Ru-PCN-777) with high stability and excellent electrochemiluminescence (ECL) performance was synthesized by immobilizing Ru(bpy)2(mcpbpy)2+ on the Zr6 cluster of PCN-777 via strong coordination bond between Zr4+ -COO-. Consequently, could not only cover surface but also graft into interior PCN-777, which greatly increased loading amount effectively prevented leaching resulting in stable ECL response....

Here, an ultrasensitive "off-on" electrochemiluminescence (ECL) biosensor was proposed for the determination of telomerase activity by using a self-enhanced ruthenium polyethylenimine (Ru-PEI) complex doped zeolitic imidazolate framework-8 (Ru-PEI@ZIF-8) with high ECL efficiency as indicator and enzyme-assisted DNA cycle amplification strategy. The Ru-PEI@ZIF-8 nanocomposites were synthesized Ru-PEI doping during growth (ZIF-8), which presented excellent stability. Furthermore, owing to...

Since aggregation-induced electrochemiluminescence (AIECL) combined the merits of emission (AIE) and (ECL), it has become a research hotspot recently. Herein, novel kinds functional metal-organic frameworks (MOFs) with strong AIECL were reported through doping tetraphenylethylene (TPE) into UiO-66. Due to porosity highly ordered topological structure that caused confinement effect MOFs, molecular motion TPE was effectively limited within UiO-66, resulting in AIE. Meanwhile, large specific...

A universal ratiometric photoelectrochemical (PEC) bioassay, which could be readily expanded for ultrasensitive determination of various targets in complex biological matrixes, was established by coupling a target-nucleotide transduction-amplification with DNA nanomachine mediated electron-transfer tunneling distance regulation strategies. With the help strategy, one input target signal transducted to corresponding multiple output signals nucleotide specific recognition technology,...

Novel luminescence-functionalized metal-organic frameworks (MOFs) with superior electrogenerated chemiluminescence (ECL) properties were synthesized based on zinc ions as the central and tris(4,4'-dicarboxylicacid-2,2'-bipyridyl)ruthenium(II) dichloride ([Ru(dcbpy)3](2+)) ligands. For potential applications, MOFs used to fabricate a "signal-on" ECL immunosensor for detection of N-terminal pro-B-type natriuretic peptide (NT-proBNP). As expected, enhanced signals obtained through simple...

The self-enhanced electrochemiluminescence (ECL) with high sensitivity could be an effective method for anticancer drug screening cell apoptosis monitoring. Here we reported ultrasensitive ECL cytosensor monitoring by using electrochemiluminescent ruthenium–silica composite nanoparticles (Ru–N–SiNPs) labeled annexin V as signal probes. Ru–N–SiNPs were first synthesized through simple hydrolysis of a novel precursor containing luminescent and intracoreactant groups in one molecule, which...
