1. A chromophoric nanoparticle comprising a semiconducting polymer having a plurality of monomeric units, wherein less than 50% of the monomeric units present in the chromophoric nanoparticle are covalently modified with a hydrophilic moiety, wherein at least one of the monomeric units is covalently modified with a hydrophilic functional group suitable for conjugation, wherein at least one of the monomeric units comprises fluorene or a fluorene derivative, and wherein the hydrophilic functional group is independently selected from the group consisting of carboxylic acid or salts thereof, amino, mercapto, aldehyde, ester, carbonyl, phosphate, cyanate, succinimidyl ester, maleimide, and substituted derivatives thereof.
