This SEM image from Silvia Todros and colleagues shows the morphology of a non-medical-grade PET industrial net. Industrial nets are used as a low-cost alternative to surgical meshes for hernia repair in less developed countries. These nets have a comparable chemical composition to hernia prostheses; however, they are knitted with multi-filament fibers which are different from surgical meshes that are commonly knitted from monofilaments. Even though physicochemical and mechanical characterization show a similarity to standard prostheses, multi-filament fibers can be considered problematic in vivo since increased infection risk and bacterial colonization have been related to a larger surface area in multi-filament fiber prostheses.
