In general, the anti-fouling property of nanoparticles depends on the stabilizing agent (Capping agent) of the nanoparticles. Many reports were published on nanoparticles with anti-fouling property (chemically synthesized/ modified and microbial derived nanoparticles). The following links may help or give some idea to you.

Fabrication of well-dispersed AgNPs on the nano-silica surface, are designated as NSAgNP, These are obtained through protein mediated reduction of silver ions at ambient temperature for development of sustainable nanotechnology. The coated proteins on AgNPs led to the formation of stable NSAgNP and protected the AgNPs from oxidation and other ions commonly present in water. The NSAgNP exhibit excellent dye adsorption capacity both in single and multicomponent systems, and demonstrate satisfactory tolerance against variations in pH and dye concentration. The adsorption mainly occur through electrostatic interaction, though π–π interaction and pore diffusion also contributed to the process. Moreover, the NSAgNP show long-term antibacterial activity against both planktonic cells and biofilms of Gram-negative Escherichia coli and Pseudomonas aeruginosa
