Quantum dots/polymer composite system for turn-on fluorescent detection of peroxide hydrogen

We report a novel method that utilizing polyethylene polyamine (PEI)/quantum dots (QDs) composite film for the detection of H 2 O 2 vapor via a fluorescence turn-on mode. It could be easily dispersed and quite stable under light irradiation. And compared with QDs-only film, the composite film is imm...

Description
Summary:We report a novel method that utilizing polyethylene polyamine (PEI)/quantum dots (QDs) composite film for the detection of H 2 O 2 vapor via a fluorescence turn-on mode. It could be easily dispersed and quite stable under light irradiation. And compared with QDs-only film, the composite film is immune to the interference signal from other volatile organic vapors thanks to that only the oxidation-reduction reaction can terminate the electron transfer process between PEI and QDs.
