Surface Patterning: Spatiotemporal Control over Molecular Delivery and Cellular Encapsulation from Electropolymerized Micro- and Nanopatterned Surfaces(Adv. Funct. Mater. 18/2009)

This frontispiece image shows a multicomponent chip inspired by a vaccine node for specific T‐cell stimulation, as described by Stern et al. on page 2888. The chip is functionalized with two different polymers (silver and black) as shown in the clockwise fabrication steps in the corners, each of which presents and releases different molecules necessary for stimulation. T‐cells are stained red and dendritic cells are stained green. The inset image shows the reverse polymer pattern.
