The antifouling properties of some carbon materials are attributed to their high surface area and sp³ hybridization. Low amount of polar functional groups on the surface of diamond particles greatly reduced the possibility of adsorption of numerous foulants. To attach the nanodiamond to the electrode it was embedded in previously prepared TMA/TMOS matrix. Observed results were analogous to pure silicate layer and no enhancement due to the presence of nanodiamond was observed (Figure ).
