Synergetic signal amplification of graphene-Fe2O3 hybrid and hexadecyltrimethylammonium bromide as an ultrasensitive detection platform for bisphenol A

- A simple strategy for graphene preparation was developed via one-step exfoliation.
- GS/Fe2O3 hybrid and CTAB exhibited notable synergetic signal amplification effects.
- An ultrasensitive electrochemical sensing platform was developed for BPA.
