Comparing topologies in nature to manmade surface to create bioactive materials
Surface texture (topography) can be used to endow biomaterials with bioactive properties. The variety of topologies available is immense and such large number of possible designs makes it challenging to find the optimal surface structure to induce a specific cell response. Currently, the TopoChip platform is the largest collection of topographies with 2176 which were designed in silico microtopographies. Inspired by the diversity of natural surfaces, the authors of a recently published article in Advanced Materials, investigated a range of topologies based on natural surfaces such as the red rose. To this end, 26 plant and insect surfaces, were replicated in polystyrene and the resulting cellular responses were assessed leading to discovery of routes to bacterial colonication and stem cell attachment and phenotype control.
