Provided is a preparation method for an immunoelectrode. The immunoelectrode comprises a substrate, a gold layer, a conductive polymer layer and an antibody layer. The substrate, the gold layer, the conductive polymer layer and the antibody layer are sequentially attached from bottom to top. The preparation method for the immunoelectrode specifically comprises the following steps: (1) preparing the conductive polymer layer: preparing a polypyrrole layer on a gold-plated substrate to obtain a polypyrrole/gold-plated substrate; (2) preparing the immunoelectrode: preparing the antibody layer on the polypyrrole layer to obtain an antibody/polypyrrole/gold-plated substrate; and (3) forming an immunoelectrode system: fixing a bare gold-plated substrate to the outer side of the antibody/polypyrrole/gold-plated substrate to obtain the immunoelectrode system. A polypyrrole material is used for fixing an antibody of a biological recognition element and immobilizing the antibody on the immunoelectrode.

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.

A binding pair for chromatographic separation or purification of a molecule of interest, where one binding member of the pair is an isomerizable organic molecule and the other binding member of the pair is an isomer-specific affinity agent bound to a molecule of interest. The binding pair associates and disassociates upon exposure to a binding agent, such as using light, decreased intensity of light, darkness, heat, stress, ions, an isomerizable affinity agent, change in pH, or a combination thereof.

A photocleavable heterobifunctional linker can include a structure of Formula (A) wherein coumarin is any coumarin or coumarin derivative; R, R.sup.9, and R.sup.10 are each independently a chemical moiety; R.sup.1 is a hydrogen, protecting group, leaving group, substrate, or capture entity; R.sup.2 is a hydrogen, hydroxyl, halide, alkoxy, anhydride, amino, protecting group, leaving group, substrate, or capture entity; L.sup.1 is a sub-linker; and L.sup.2 is a sub-linker. A capture device can include the photocleavable bifunctional linker having a structure of Formula (A) as provide herein, wherein R.sup.1 is a substrate. A method of capturing a target substance can include: providing the capture device having the photocleavable bifunctional linker with the structure of Formula (A) and contacting a target substance to the capture moiety such that the target substance is captured. Irradiating the linker with light can cleave the linker, thereby releasing the target substance from the substrate.
