PD is a novel polymer offering properties similar to polystyrene, but has a much lower oxygen permeability, which results in a higher photostability for most dyes. The size is about 40 nm and the surface can be either carboxylated or additionally modified. All particles are offered in a 0.5% (w/w) aqueous suspension in buffer (10 mM MES, pH 7).
