Abstract
Cell patterning on photo-responsive materials are a promising tool for preparing unique single-cell arrays. However, most conventional single-cell arrays on such smart materials can be applied only to adherent cells and limit cellular functions such as extension and migration within the patterned adhesive surfaces. In this study, a versatile single cell array that works with both non-adherent and adherent cells was constructed using a photo-cleavable polyethylene glycol (PEG)-lipid/collagen surface. On this single-cell array, cells behaved similar to their native functions without limitation from the patterned surface. Furthermore, quantitative imaging analyses of cellular motility and morphological changes were performed in a high-throughput manner.
