Claims21
A nanoparticle comprising:
- a polymer dot comprising a condensed semiconducting polymer;
- and
- a polyelectrolyte coating that surrounds the condensed semiconducting polymer, the polyelectrolyte coating comprising a first polyelectrolyte polymer and a second polyelectrolyte polymer, wherein the first polyelectrolyte polymer is poly(styrene sulfonate) and the second polyelectrolyte polymer is poly(sodium methacrylate).
A plurality of nanoparticles comprising:
- a nanoparticle comprising:
- a polymer dot comprising a condensed semiconducting polymer dispersible in an aqueous solution;
- and
- a polyelectrolyte coating that surrounds the condensed semiconducting polymer, the polyelectrolyte coating comprising a first polyelectrolyte polymer and a second polyelectrolyte polymer, wherein the first polyelectrolyte polymer is poly(styrene sulfonate) and the second polyelectrolyte polymer is poly(sodium methacrylate).
