Linker structures with minimal scar for enzymatic synthesis
This disclosure provides electrochemically-cleavable linkers with cleavage potentials that are less than the redox potential of the solvent in which the linkers are used. In some applications, the solvent may be water or an aqueous buffer solution. The linkers may be used to link a nucleotide to a bound group. The linkers include a cleavable group which may be one of a methoxybenzyl alcohol, an ester, a propargyl thioether, or a trichloroethyl ether. The linkers may be cleaved in solvent by generating an electrode potential that is less than the redox potential of the solvent. In some implementations, an electrode array may be used to generate localized electrode potentials which selectively cleave linkers bound to the activated electrode. Uses for the linkers include attachment of blocking groups to nucleotides in enzymatic oligonucleotide synthesis.

Method for preparing products by electrochemical reductive amination and simultaneous oxidation of aldehyde-based biomass using non-precious metal catalysts
A method for preparing products by electrochemical reductive amination and simultaneous oxidation of aldehyde-based biomass using non-precious metal catalysts is provided, which relates to a field of electrocatalysis. The preparing method includes: performing an electrochemical reaction in an electrolytic system with room temperature and atmospheric pressure (at a range of 25° C. to 30° C., 101 kPa) by taking an aldehyde compound and an amine compound as raw materials for reductive amination and oxidation of aldehyde-based biomass, and thereby obtaining the products. The electrolytic system includes a reaction substrate, an electrolyte, a solvent, an anode and a cathode. The anode is a phosphorylated hydrotalcite catalyst and the cathode is a Ti-based catalyst. The method uses no external oxidants and precious metal catalysts, which is clean, environmental and efficient.

By-products (impurity) removal
An electrolytic reactor comprises at least one electrolytic cell with an anode compartment and a cathode compartment separated by a separator, in particular a semipermeable membrane. The anode compartment comprises an inlet and an outlet for anolyte at opposed ends, said inlet and outlet being connected with each other via an anolyte circulation pipe equipped with a storage means for anolyte, an anolyte vessel and at least one adsorption filter for adsorbing molecular impurities. When molecular impurities comes from the cathode compartment through the separator, the electrolytic reactor acts also as a cleaning device for the catholyte.
