title: CEA fluorescence biosensor based on the FRET between polymer dots and Au nanoparticles.
abstract: Polymer dots were employed as luminophors to design a fluorescence biosensor for carcinoembryonic antigen (CEA) with high sensitivity and selectivity; the increased fluorescence intensity is proportional to CEA concentration in the range of 0.1-10 ng mL(-1).
