Durable polyurea copolymer coatings can be applied to surfaces that come in contact with fluids, such as biological fluids, thereby passivating the surface. Polyurea copolymer coating compositions comprise a reaction product of (a) a diamine composition that includes a polyethylene glycol diamine, and optionally, a dipiperidyl alkane; and (b) a diisocyanate. Solutions containing polyurea copolymers, coated surfaces and methods are also described.

Polyurea copolymer coating compositions and methods

Inventive concepts relate generally to nanofibrous scaffolds useful for electrophysiological assays. Scaffolds include polymeric nanofibrous components and electrically excitable cells immobilized at a distinct cell seeding domains on the scaffold. Methods and kits including the scaffolds are also described.

Tissue scaffolds for electrically excitable cells

The invention describes novel coating agents that include a polymer, one or more latent reactive groups and one or more noncovalent linking groups, the noncovalent linking groups selected to interact with a substrate to which the coating agent is applied. The coating agents are useful for providing a coating that can be further functionalized (for example, by application of additional coating layers), or for providing desirable properties to a surface.

Coating agents and coated articles

The invention describes novel coating agents that include a polymer, one or more latent reactive groups and one or more noncovalent linking groups, the noncovalent linking groups selected to interact with a substrate to which the coating agent is applied.

The invention is directed to transfection reagents for the delivery of nucleic acids into neural cells, compositions including the reagents, methods of preparation of such reagents, methods of transfecting cells with such reagents, and uses thereof. In preferred embodiments the reagents comprise horseradish peroxidase and/or a polycarboxylic acid such as poly(acrylic acid) or poly(methacrylic acid).
