The cellular behavior and toxicity effect of organometallic complexes depend largely on their peripheral ligands. In this study, we have synthesized a series novel luminescent cationic iridium(III) by tuning the ancillary N(∧)N ligand based structure [Ir(ppy)2(N(∧)N)](+) (ppy = 1-phenyl-pyridine; 2,2'-bipyridine (bpy, 1) or phenanthroline (phen, 2) 4,7-diphenyl-1,10- (DIP, 3)). As size coordinated increases, absorbance/emission efficiency, quantum yields, lipophilicity, cell uptake rates...
Mutations in the adult human skeletal muscle Na + channel a subunit cause disease paramyotonia congenita. Two congenita mutations, R1448H and R1448C, substitute histidine cysteine for arginine S4 segment of domain 4. These expressed cell line, have only small effects on activation Na+ currents, but mutant channels inactivate more slowly with less voltage dependence than wild-type exhibit an enhanced rate recovery from inactivation. Increase extracellular pH made inactivation RI 448H similar...
Lighting up the cell: Peptides that are site-specifically labeled with a luminescent iridium(III) complex at histidine residues can penetrate cell membranes effectively, showing intracellular distribution and efficient mitochondrial targeting (see figure, CPP=cell-penetrating peptide, MTS=mitochondria-targeting sequences). Detailed facts of importance to specialist readers published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available...
Tuberculosis (TB) remains one of the leading causes morbidity and mortality all over world multidrug resistance TB (MDR-TB) pose a serious threat to control represent an increasing public health problem. In this work, we report homogeneous signal-on electrochemiluminescence (ECL) DNA sensor for sensitive specific detection rpoB genes MDR-TB by using ruthenium(II) complex functionalized graphene oxide (Ru–GO) as suspension sensing interface ferrocene-labeled ssDNA (Fc–ssDNA) ECL intensity...
Centipedes can subdue giant prey by using venom, which is metabolically expensive to synthesize and thus used frugally through efficiently disrupting essential physiological systems. Here, we show that a centipede ( Scolopendra subspinipes mutilans , ∼3 g) mouse (∼45 within 30 seconds. We found this observation largely due peptide toxin in the SsTx, further established SsTx blocks KCNQ potassium channels exert lethal toxicity. also demonstrated opener, retigabine, neutralizes toxicity of...
Under well-controlled conditions, different polypyrrole variants can be galvanostatically prepared in acetonitrile + 1% H2O by changing the current density. At densities down to 0.25 mA/cm2, PPy(I) is electrosynthesized; at lower densities, a mixture of and PPy(II) generated. In presence small amount acid (∼1 × 10-5 M), exclusively formed. The availability well-defined materials enables us perform further reliable characterization EQCM. results reveale natures ionic transport when PPy are...
Five iridium(III) complexes with two N-heterocyclic carbene (NHC) ligands and an ancillary ligand have been designed successfully synthesized. With multicolor photoluminescence low toxicity, these were tested, for the first time, as living cell imaging reagents showed promise application beyond OLED (organic light emitting diode) area.
Sky-blue homoleptic iridium(<sc>iii</sc>) complexes with phenylimidazole ligands show consistent behavior that is linked to their ligand conjugation.
In acetonitrile electropolymerization of pyrrole is considerably facilitated by the addition a small amount water. Several mechanisms have been suggested in past to interpret this dramatic influence However, none them has explained all experimental results obtained up now. On basis mechanism involving acid-catalyzed formation trimer, 2,2‘-(2,5-pyrrolidinediyl)dipyrrole and its subsequent leading electrode passivation, it proposed that water, fairly strong base acetonitrile, prevents trimer...
Ultrasensitive bioanalytical assays are of great value for early detection human diseases and pathogens. The sensitivities immunoassays DNA probing can be enhanced by multilabeling the biorecognition partner used affinity-based assays. However, bioreactivity biomolecules is affected a high degree at multiple functional sites. It proposed that dendritic scaffoldings to link signal-generating units single site with potentially minimum impact on bioaffinity. A prototype label, zeroth-generation...
Several [Ru(bpy)3]2+ (bpy = 2,2'-bipyridine and its derivatives) complexes were synthesized compared electrochemically spectroscopically in the search for better luminophores electrochemiluminescence (ECL)-based analytical applications. ECL measurement [Ru(bpy)3]2+/tripropylamine (TPA) aqueous buffer solutions has led to a conclusion that due complexity of generation process, photoluminescence efficiency cannot be used predict intensity there is no obvious relationship between quantum yield...
Two series of (dfppy)2Ir(LN^O) with different substituents were designed and successfully synthesized the effect substitution at ancillary ligand on photophysical electrochemical properties investigated. The results indicate that electron-donating group –OMe LN^O increases PL quantum efficiencies electron-withdrawing groups –CF3 –F lower efficiencies.
A series of cyclometalated iridium(III) complexes with 2-phenylquinoline ligand (1-4) were designed and synthesized, which thoroughly investigated by the photophysics, electrochemistry, theoretical calculations electrochemiluminescence (ECL). By incorporating methyl groups into 2-phenylquinoline, corresponding 2 3 displayed lower oxidative potential higher HOMO energy levels. Most importantly, compared tris(2,2'-bipyridyl)ruthenium(II) ([Ru(bipy)3](2+)), these demonstrated more intense ECL...
