A novel pH-controlled immunosensor using hollow mesoporous silica and apoferritin combined system has been reported for the first time. The goal of this study was to introduce more electroactive probes into the electrochemical immunosensor. Under such background, we focused our attention on hollow mesoporous silica and apoferritin, both of which have(More)
In the title compound, [Pd(C8H4O4)(C7H6N2)2]n, the Pd atom is tetracoordinated by two carboxylate O atoms from two benzene-1,4-dicarboxylate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetrahedral PdO2N2 geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N— H O(More)
This paper introduced the significance parameters of the quality control of cold light source of endoscope, expounded the importance and necessity of quality control of cold light source; it investigated several manufacturers, analyzed and discussed the main causes of the cold light source uneven, in order to realized the standard management and effective(More)
In the title compound, [Mn(2)O(C(18)H(18)ClN(4))(2)](PF(6))(2), the Mn atom is chelated by a tetra-dentate ligand via four N atoms, and further bonded to one chloride ion and one bridging oxide, to give a centrosymmetric cation and distorted octa-hedral coordination geometry.
In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain.(More)
In the title compound, [Fe(2)(C(16)H(12)Br(2)N(2)O(2))(2)O], the complete mol-ecule is generated by twofold symmetry, with the bridging O atom, which links the iron centres, lying on the roatation rotation axis. The Fe(III) ion is chelated by the N,N,O,O-tetra-dentate Schiff base dianion, resulting in an FeN(2)O(3) square-based pyramid, with the two N atoms(More)
The Mn(III) ion in the title complex, [Mn(C(15)H(10)N(3)O)(2)]ClO(4)·H(2)O, is coordinated meridionally by six N atoms from two tridentate N-(8-quinol-yl)pyridine-2-carboxamidate ligands, yielding a distorted octa-hedral coordination geometry. The two ligands are nearly planar and their mean planes are almost perpendicular, with a dihedral angle of 86.7(More)
