Nanocylinders: Lithography‐Free Fabrication of Silica Nanocylinders with Suspended Gold Nanorings for LSPR‐Based Sensing (Small 48/2016)

A dense array of fused silica nanocylinders is achieved using lithography-free reactive ion etching, as presented by A. H. Thilsted and co-workers on page 6745. Varying the etching parameters allows for control of the height and diameter of the nanocylinders. A subsequent gold deposition results in suspended gold nanorings at the tops of the nanocylinders that exhibit localized surface plasmon resonance that can be used for biosensing.
