Abstract: Dye-labeled polymers formed from a polymer and a dye are disclosed. Methods for labeling a polymer with a dye are also disclosed. The polymer can have any weight average molecular weight (Mw), particularly a Mw of > 5 megadalton (MDa) or > 6 MDa. The polymer contains reactive group(s) that can be activated by an activation agent in a buffer solution. Upon activation, the polymer bundles and forms activated polymer in a solid form. The activated polymer can react with a reactive group of the dye to form the dye-labeled polymer. By soaking the dye-labeled polymer in a solid form in an aqueous solvent, the dye-labeled polymer can regain the viscosifying property that is the same or substantially the same as the polymer prior to labeling with the dye.
