A novel procedure for fluorescent sensing of histamine was developed using surface molecular imprinting on quantum dots modified by ionic liquid. The sensing material was synthesized via a facile one-pot route on the surface of CdSe/ZnS quantum dots (QDs), and in this process, ionic liquid (IL) was successfully introduced by electrostatic interactions to strengthen the fluorescent stability of QDs and the fluorescence sensitivity of the synthesized materials that was called QDs@IL@MIP. QDs@IL@MIP was characterized by fluorescence spectrophotometer, scanning electron microscopy (SEM), and infrared spectroscopy. The fluorescence of QDs@IL@MIP can be strongly enhanced by histamine (HA) which can be determined in a wide concentration range of 0.449–2.249 mM with a low limit of detection (LOD) of 0.11 mM.
