•Original diamond coating process adapted to a wide variety of porous substrates•New self-supported diamond porous membranes with tunable pore size from few tens of micrometers to few tens of nanometers•Suitable devices for analytical chemistry: high flow filtration, separation/extraction and high surface area electrodes•Diamond membranes used for proteins extraction, recovery improvement through straightforward surface functionalization
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. Such membranes 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 porous membranes' 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.
