The present technique provides a simple, cost-effective and robust method for re-alignment of interfaces between cell conjugates parallel to the coverslip. The technique is based on placement of two cell types, to subsequently form an interaction between the cell types, to opposing coverslips and then bringing them together before or during imaging, for either fixed or live cell imaging. Spacer particles having defined parameters control the z-separation and the relative lateral position of the opposing coverslips. We show that our method allows most types of super-resolution imaging.
