Preparation of heteroatom doped poly(o-phenylenediamine) fluorescent nanospheres: Tunable fluorescent spectrum and sensing performance

- The heteroatom doping progress changed the fluorescent spectrum and sensing performance of PoPD fluorescent nanospheres.
- The heteroatom doped and undoped fluorescent nanospheres have excellent fluorescent properties.
- The heteroatom doped and undoped PoPD fluorescent nanospheres are ultra-sensitive fluorescent probes (ppb level).
- These fluorescent probes are ultrasensitive and showed excellent selectivity, specificity and anti-interference ability.
- The internal mechanism on this process is also discussed.
