Surface Modifications of Breast Implants affect Immune Response.

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).
