摘要:
The present invention relates to the field of film materials for biosensors, in particular to a film for biosensors and a preparation method. Provided is an organosilicon polymer, the raw materials thereof comprising the following components: at least one active organosiloxane, at least one curing agent, at least one optional hydrophilic copolymer and at least one optional regulator and/or filling. The membrane prepared from the provided organosilicon polymer has outstanding oxygen permeability and is adjustable in water absorption rate, and can put regulation and restriction on the diffusion of analytes (e.g. glucose) and interferents (e.g. acetaminophen). Meanwhile, the provided organosilicon polymer film also has indispensable physical strength and superior biocompatibility, and can serve as a multifunctional polymer film material for biosensors, such as anti-interference layer, analyte regulating layer and biocompatible layer.
摘要:
A process for the production of a glycoconjugate by N-glycosylation of a protein or peptide comprising the sequence D/E-X—N—X—S/T, wherein each X is the same or different and is any natural amino acid other than proline, wherein the process comprises reacting the protein or peptide with a polyisoprenyl pyrophosphate of formula (I), or a salt thereof, in the presence of PglB: (I) to produce the glycoconjugate comprising the protein or peptide having a saccharide [SI] linked to the asparagine in the sequence D/E-X—N—X—S/T. Polyisoprenylpyrophosphates used as substrates in the biocatalytic process are also provided, as well as certain glycoconjugates.
摘要:
The present invention provides a cathode active material on which at least one coating layer is formed, a method for manufacturing the same, and a lithium secondary battery including the same. According to the present invention, since the coating layer with high electrical conductivity is formed on a surface of the cathode active material, the electrical conductivity is improved to enhance charge/discharge and cycle life characteristics and thermal stability of the battery.
摘要:
A method of improving the thermal transfer properties of a heat transfer surface (1) of a heat exchanger element by electroless deposition on the surface (1) of a coating (2) of a metal or a metal alloy, preferably of nickel or copper or their alloys, optionally with particulates of silver or chlorinated or fluorinated polymers. The electroless deposition is carried out for a shortened period of time, which creates a surface which is rough at the nano scale, including asperities of the order of hundreds of nanometres in size. The surface is also of low surface energy, highly hydrophobic and has a high surface area. The surface is a biomimetic hierarchical nanostructure.
