Abstract
Small-sized semiconducting polymer dots (Pdots) provide better tissue and subcellular penetration while minimizing unspecific interactions, and make the fast clearance of Pdots from human bodies possible by urinary excretion. We employ a powerful and scalable technology, flash nanoprecipitation, to prepare Pdots with small sizes (hydrodynamic diameters ∼10 nm).
