Create Special Surfaces for Your Cells
This process transfers a sample liquid called “ink” onto a planar target surface. The PDMS stamp is inked with the sample, subsequently pressed onto the surface, thereby transferring the sample only from the high areas, as in letterpress printing.
Not only chemicals, but also biomolecules, nanoparticles, beads, or cells can be printed. Patterns of proteins like fibronectin or laminin can serve as adhesive substrate to grow cells only on protein-covered areas.
µCP4.1 automatically uses up to five stamps with different inks and different patterns for well aligned prints on the same substrate.
