To observe the surface morphology of the synthesized materials, the composites were characterized using a scanning electron microscope (SEM). Fig. 1 shows the SEM images of Ni–MOF, β-CD and β-CD/Ni–MOF. Fig. 1A and 1B show that Ni–MOF is connected with each other in a three-dimensional spherical structure with relatively uniform form and large specific surface area, and contains a large number of pores inside, which is conducive to accelerating the diffusion rate of guest molecules.

Dopamine (DA) is an important neurotransmitter in human's brain, which has direct connection to diseases like Parkinson's disease, schizophrenia, etc. Therefore, the sensitive and rapid quantitative detection of DA is essential for medical diagnosis and disease prevention. To construct a novel electrochemical sensor for DA detection, nickel-based metal-organic frameworks (Ni-MOF) were synthesized through a hydrothermal method and combined with beta-cyclodextrin. Under optimal experimental conditions, the sensor exhibited a wide linear detection range (0.7-310.2 mu M) and a low detection limit ...
