An automatic method is established for layer-by-layer (LbL) assembly of biomimetic coatings in cell culture microplates using a commercial liquid-handling robot. Highly homogeneous thin films are formed at the bottom of each microwell. The LbL film-coated microplates are compatible with common cellular assays, using microplate readers and automated microscopes. Cellular adhesion is screened on crosslinked and peptide-functionalized LbL films and stem cell differentiation in response to increasing doses of bone morphogenetic proteins (2, 4, 7, 9). This method paves the way for future applications of LbL films in cell-based assays for regenerative medicine and high-throughput drug screening.
建立了一种使用商用液体处理机器人在细胞培养微孔板中逐层(LbL)组装仿生涂层的自动方法。在每个微孔的底部形成高度均匀的薄膜。LbL 薄膜涂覆的微孔板与常见的细胞测定法兼容,可使用微孔板读数器和自动显微镜。在交联和肽功能化的 LbL 薄膜上筛选细胞黏附,并响应骨形态发生蛋白(2、4、7、9)的递增剂量检测干细胞分化。该方法为 LbL 薄膜在基于细胞的再生医学和高通量药物筛选测定法中的未来应用铺平了道路。
