Further evidence of the important effect of engineered surfaces on immune response, this time in breast implants. Such research demonstrates the importance of modifying the surface texture in a manner that reduces the foreign body response. These and other examples pave the way for the development of new technologies for enhancing a favourable response to the implant and reduce complications including, potential, arising from infection and surface contraction.
The authors of the original paper have already provided a classification system for functional biocompatibility with regard to surface roughness (see figure below).
