摘要:
The present invention relates to method of surface modifying a hydrogel using microcontact printing or photolithography or inkjetand hydrogels obtained by said method.
摘要:
The present invention relates to a corneal implant comprising a matrix material and a core part wherein the core part is arranged essentially in the middle of the matrix material. The core part is anti fouling in order to stop cell proliferation across said part. The present invention further relates to a method of preparing the said product and the use of the same.
摘要:
Guanidinyl ligand-functionalized polymers, methods of making the same, and substrates bearing a grafted coating of the ligand-functional polymers are described. The grafted polymer has the requisite affinity for binding neutral or negatively charged biomaterials, such as cells, cell debris, bacteria, spores, viruses, nucleic acids, endotoxins and proteins, at pH's near or below the pI's of the biomaterials.
摘要:
The invention relates to radiation-curable acrylated polyaminoamides that are obtained by Michael-Addition of polyaminoamides with terminal amine groups (A) and polyol ester acrylates (B). The molar ratio of the acrylate groups in the polyol ester acrylates (B) in relation to the amino-hydrogen groups in the polyaminoamides (A) is at least 1 : 1. Said invention is characterised in that the polyaminoamides (A) have an amine value of more than 115. Said acrylated polyaminoamides are suitable as radiation-curable compounds for producing coatings.
摘要:
A modified polyurethane including a lipid substituent pendant from at least one urethane nitrogen and/or at least one carbon atom of the modified polyurethane, methods of preparing modified polyurethanes and the use thereof as an implantable biomaterial. Figure 2 shows the steps for making polyurethane having cholesterol pendent from a urethane nitrogen.
摘要:
The present invention refers to a waterborne copolymer dispersion comprising at least one alkenyl functional dendritic polymer being copolymerised to the polymer backbone of at least one homo or copolymer obtainable by polymerisation, such as emulsion polymerisation, in an aqueous medium of at least one at least one polymerisable allyl, vinyl, maleic or diene monomer. Said dendritic polymer is built up from a dendritic core polymer and at least one alkenyl functional compound bonded to said core polymer. In a further aspect the present invention refers to the use of said copolymer dispersion.
摘要:
The invention relates to methods of treating mixtures containing polymeric materials, e.g., collagen, to form a polymer that intercalates into the polymeric material. The treatment provides greater tensile strength to the mixture, among other advantages. The polymer is formed of a monomeric unit having at least one catechol group that is oxidized to a quinone upon polymerization.
摘要:
The present invention relates to a novel solid support template of Formula (I) and methods for producing novel highly functionalized imidazoles, pyrazinones and benzodiazepinones through a plurality of chemical reactions utilizing the solid support template.
