Other applications

Most of the structures that we make have dimensions between 10 nm and up to a few microns. The length scale does not only contain the wavelength of visible light, but it also contains the size range of human cells. DNA strands are somewhat smaller in width, but the fluidic networks used to manipulate DNA are in fact within the range as well. So additional to all the optical applications, there are many applications within Biotech – both indirectly through fluidic networks that transport biological material in lab-on-a-chip devices, or directly by making structures that interact with cells.

An example of the latter are surfaces where it is difficult for bacteria to grow. Structured antibacterial  surfaces is an area of interest for both medical equipment and the food industry. Another area where this could be used is to prevent growth of biological material on surfaces used for marine applications.

Moreover, the bio-mimicking trend of seeing how nature designs surfaces and making artificial copies that respond in a similar way, is helping the development of new applications relating to how surfaces interact with water. By controlling the hydrophobicity, it is possible to investigate applications like anti-fog or self-cleaning surfaces, but also how to reduce friction. Swimsuits resembling shark skin is an example of this.

We look forward to hearing about what challenges you are facing and if there is a solution by structuring the surface.
