Imprinting of natural surfaces
Nature as a source of inspiration
Living nature has become an inspiration for modern innovations and keeps providing solutions to the technical challenges. Recently, many nanomaterials, nanodevices, functional surfaces, etc. were developed and enhanced by mimicking biology and nature. Particularly, insects and plants are the two widely studied organisms due to their superhydrophobic and self-cleaning properties. For instance, rice and butterfly wing effect is a consequence of combining unique surface characteristics also found on shark skin (antifouling) and lotus leaf (self-cleaning). At cBITE, we continue to explore the fascinating possibilities by replicating surfaces found in the Amazon rainforest of Ecuador and conducting physicochemical testing on them to elucidate the properties of these micro- and nanostructures.
