description

Abstract For investigation of spatial effects in signalling between cells and also signal substances that trigger cell proliferation and behaviour we are developing a micro Contact Printing process ( μ CP ) . In order to allow printing of cells stamps with high aspect ratio are required and these have been fabricated using Programmed Proximity Aperture Lithography (PPAL) with 3 MeV 4 He 2 + ions to produce PMMA masters for casting the stamps in PDMS. A simple printing device was developed and the first results using this to print human osteosarcoma cells is demonstrated.
