High‐Aspect‐Ratio Nanostructured Surfaces as Biological Metamaterials [PDF]

open access: yesAdvanced Materials, 2020
AbstractMaterials patterned with high‐aspect‐ratio nanostructures have features on similar length scales to cellular components. These surfaces are an extreme topography on the cellular level and have become useful tools for perturbing and sensing the cellular environment. Motivation comes from the ability of high‐aspect‐ratio nanostructures to deliver

High-aspect-ratio nanoimprint process chains [PDF]

open access: yesMicrosystems & Nanoengineering, 2017
AbstractDifferent methods capable of developing complex structures and building elements with high-aspect-ratio nanostructures combined with microstructures, which are of interest in nanophotonics, are presented. As originals for subsequent replication steps, two families of masters were developed: (i) 3.2 μm deep, 180 nm wide trenches were fabricated ...

Flux-closure domains in high aspect ratio electroless-deposited CoNiB nanotubes

open access: yesSciPost Physics, 2018
We report the imaging of magnetic domains in ferromagnetic CoNiB nanotubes with very long aspect ratio, fabricated by electroless plating. While axial magnetization is expected for long tubes made of soft magnetic materials, we evidence series of ...
