In this study, novel diamond porous membranes are developed through a reliable process providing a unique
pathway toward large surface area and porous materials. Mainly deposited onto flat surface so far, we demonstrate
here that diamond coating is possible on very complex 3D shapes, even nanoporous ones, through an original
nanoseeding process and adapted growth conditions. Suchmembranes or filters exhibit outstanding features
thanks to the unique mechanical properties and surface chemistry of diamond. Indeed, the straightforward
tuning of their surface properties associated to their high stability ensures the diamond porousmembranes' applications
in the scope of filtration, separation and extraction. Preliminary electrochemical studies highlight the
membranes' potential to be used for high specific area electrode applications. After an extensive characterization
of these new diamond porous membranes, their potential for protein extraction will be demonstrated through
mass spectrometry detection.
