Аннотация: Abstract—A method is proposed for controlling the wettability of the surface of a fluorinated material and for controlling its biofouling by introducing modified nanodiamonds into the structure. The optimal modification conditions were determined by means of a set of methods based on the example of a molecular oxygen sensor. They do not lead to a change in other functional properties of the material, such as the calibration curve and response time. In vitro tests have shown that a small amount of aminated nanodiamonds gives the surface bactericidal properties, but with a high content, improved adhesion of the biomaterial is observed due to a decrease in hydrophobicity. Long-term in situ tests under conditions simulating a bioreactor with actively growing biomass showed an almost complete absence of biological fouling of the modified material and revealed a significant fouling of the sensor from traditionally used polystyrene.
