The linear concentration range for the proposed electrodes was between 10−11 and 10−4 mol L−1, with the lowest detection limit (2.46 pmol L−1) obtained using the diamond paste dot-sensor modified with zinc-5,10,15,20-tetra(4-sulfophenyl)porphyrin. 4-sulfophenyl porphyrin
A second group of mice receive human stem cells that have been modified with the zinc finger nuclease.
The subjects' own stem cells will be modified with the zinc finger nucleases that disrupt the gene for the CCR5 receptor.
Then, the polymer coatings were modified with deposition of zinc particles (∼ 1 mg/cm2), at a constant potential value of − 1.20 V in 0.2 M ZnSO4 solution.
Furthermore, the photoelectrodes were modified with indium sulfide and/or zinc sulfide phases via successive ionic layer adsorption and reaction (SILAR).
Two porphyrinato-zinc derivatives modified with two and four N,N-di 2-pyridylmethyl)amiN,N-di 2-pyridylmethylorphyriN,N-di 2-pyridylmethylphyrin-4-DPamino, have been desigroupssynamelyzed, and characterized.
The design and synthesis of an asymmetrical zinc phthalocyanine sensitizer modified with a catechol anchoring group is reported.
In some cases, these metal contacts are replaced by transparent conductive oxide (TCO), such as tin oxide [24] or zinc oxide [25], modified with dopants such as fluoride or aluminium, respectively.
Here we describe an advance in the catalysis of the overall splitting of water under visible light: the new catalyst is a solid solution of gallium and zinc nitrogen oxide5,6, (Ga1−xZnx)(N1−xOx), modified with nanoparticles of a mixed oxide of rhodium and chromium.
We performed a selective labeling strategy whereby the cysteine residues exposed upon removal of zinc from the enzyme were modified with [3H]NEM.
