It shows that the carboxyl group or the group of sulfonyl hydroxide can form a H-bond with key residue Arg316 in the docking pose.
The method is comprised of attaching a reactive group X--Y to a surface of a pigment; and subsequently displacing Y with an organic substrate N--S--ZM to form a surface-modified pigment having attached X--N--S--ZM; wherein X is a sulfonyl, phosphoryl, or 1,3,5-triazine group; Y is fluorine, chlorine, bromine or iodine; N is an amine, an imine, a pyridine, or a thiol group; S is substituted or unsubstituted alkyls, aryls, or polymer chains having a molecular weight range from approximately 300-8000; Z is a carboxyl, sulfonyl, phenolic, phosphoryl, ammonium, trimethylammonium, or tri-butylammonium group; and M is a halide, a negatively charged ion, a proton n salt form, or a cation in salt form.
