Fabrication of nanoparticles with phenol and alkyne functional groups and their size distribution after surface modification. (A) The schematic of the surface modifications used and the surface functional groups present on the nanoparticles. (B) The as-fabricated nanoparticles containing both functional polymers and (C) the size distribution of the particles after collection and surface modification with linear or star PEG molecules. The scale bar in (B) is 500 nm.
