An ultrasensitive electrochemical bisphenol A sensor based on hierarchical Ce-metal-organic framework modified with cetyltrimethylammonium bromide

We designed an ultrasensitive electrochemical bisphenol A sensor using hierarchical Ce-metal-organic framework modified with cetyltrimethylammonium bromide as sensing platform, the dual amplification made the proposed bisphenol A sensor have a wide linear response ranging from 0.005 to 50 μmol L−1 with a low detection limit of 2.0 nmol L−1.
