The present invention pertains to a process for producing three-dimensional, self-supporting and/or substrate-supported formed pieces or structures on surfaces by means of site-selective solidification of a liquid to pasty, organic or organically modified material within a bath consisting of this material by means of two- or multiphoton polymerization, whereby the material has at least one compound that has both an organic radical polymerizable via two-photon or multiphoton polymerization and a biocompatible, biodegradable or bioresorbable group, and/or wherein the bath material additionally contains groups or radicals, which are available for an inorganic crosslinking or which are already inorganically crosslinked, providing that both an organic radical polymerizable via two-photon or multiphoton polymerization and a biocompatible, biodegradable or bioresorbable group must be contained in the material. The formed pieces or surface structures according to the present invention are suitable as matrices for binding live cells, which can be multiplied after that or stimulated for the production of specific substances. They can be used, e.g., as an extracorporeal [sic—Tr.Ed.] matrix or as an implant.
本发明涉及一种通过在由该材料组成的浴中,通过两光子或多光子聚合将液体固化为糊状有机或有机改性材料,以在表面上产生三维自支撑和/或基底支撑的形成件或结构的方法,其中该材料至少具有一种化合物,该化合物具有通过两光子或多光子聚合可聚合的有机基团和
生物相容性、
生物可降解或
生物可吸收的基团,和/或浴材料另外含有可用于无机交联或已经无机交联的基团或基团,前提是材料中必须同时含有通过两光子或多光子聚合可聚合的有机基团和
生物相容性、
生物可降解或
生物可吸收的基团。根据本发明的形成件或表面结构适用于作为绑定活细胞的基质,之后可以进行细胞增殖或刺激特定物质的生产。它们可以用作体外基质或植入物。
