| Abstract: | Polyelectrolyte multilayer formed through electrostatic attraction was assembled on gold nanorods.Gold nanorods without polymer layer quenched the fluorescence of fluorescein,and its quenching yield was 91.5%.Gold nanorods with polyelectrolyte layers enhanced the fluorescence of fluorescein.The corrected enhancement factor reached 102. |
