Abstract

We present a simple method for the fabrication of separated brush-like networks with both improved optical and biological properties. The brush networks were fabricated by combing the glancing angle deposition (GLAD) technique with colloidal mask templating. By changing the deposition angle during GLAD on the template layers as the amount of platinum deposited per area [surface mass density (g cm−2)] it is possible to create a wide range of reproducible and localized brush-like networks consisting of high aspect ratio whiskers with different sizes and morphologies. The results presented here indicate that localized surface plasmons are present on the GLAD templated surfaces while cell assays with monocyte cells showed an impaired attachment to the brush structures. Consequently, deposition by means of a colloidal mask templating is indeed a very tunable and suited technique for the fabrication of multifunctional nanomaterials which could have potential impact on devices where both controlled optical properties and cell surface interactions are needed (for instance controlled cell adhesion on optical biosensor materials).
