Ligand Nano-cluster Arrays in a Supported Lipid Bilayer

Currently there is considerable interest in creating ordered arrays of adhesive protein islands in a sea of passivated surface for cell biological ...

Arrays of protein nanodots with dot-size tuned independently of spacing (e.g., ∼100 to 600 nm diameter for 900 nm spacing) are fabricated. The mechanism of size control is demonstrated, by numerical simulations, to arise from shadow effects during deposition of a sacrificial metal mask. We functionalize the nanodots with antibodies and embed them in a polymer-cushion or in lipid-bilayers or transfer them to soft elastomers. Their ability to influence cell architecture and local membrane organization is demonstrated in T-lymphocytes, using reflection interference contrast and total internal reflection fluorescence microscopy.
