摘要:
The invention provides cell-adherent polymeric coatings for articles having a nanofibrillar structure. The coatings include a synthetic, non-biodegradable polymer having at least one pendent amine group, wherein the polymer is covalently immobilized on the article via latent reactive groups. The invention also provides methods for the long term culturing of cells using the polymer coated nanofibrillar structures. The polymer coated nanofibrillar structures of the invention have been found to be particularly useful for the growth and differentiation of cells, including neural precursors.
摘要:
The invention provides cell-adherent polymeric coatings for articles, the coating including a synthetic, non-biodegradable polymer having a plurality of pendent amine groups, wherein the polymer is covalently immobilized on the article via latent reactive groups. The invention also provides methods for the long-term attachment of cells using the polymeric coatings.
摘要:
The invention provides methods for forming ultra-thin hydrophilic polymeric coatings on articles, as well as articles formed therefrom. The coatings are formed by irradiating a composition including a polymer having pendent photoreactive groups while the composition is in contact with a surface of the article.
摘要:
The present invention relates to compositions suitable for spotting compounds onto a substrate, and methods employing these compositions. The composition can include one or more organic anions of formula I: R(X)m(Y)n. In an embodiment of formula I, R is an organic moiety, X is an anionic moiety, and, Y is a neutral hydrophilic moiety. The composition can include one or more neutral hydrophilic polymers. In an embodiment, the neutral hydrophilic polymer can be represented by formula V: In Formula V, the group in parenthesis represents the polymer backbone, A can be absent or is a carbon or a heteroatom, and B is pendant neutral hydrophilic group. The present invention includes arrays, which can be made with or include compositions according to the present invention and can be made by using the method of the present invention.
