Polymer dots (Pdots) have emerged as a new type of fluorescent probe material for biomedical applications and attracted great interest due to their excellent optical properties biocompatability. In this work, we report on red-emitting P3HT Pdot intracellular bioimaging. The as-prepared exhibits good stability has large Stokes shift (121 nm) compared molecules in tetrahydrofuran (THF). Furthermore, the shows low cytotoxicity, broad absorption spectrum, resistance against photodegradation, water dispersibility. These advantageous characteristics make Pdots promising
