Abstract A fluorometric method for the determination of histamine has been developed based on aggregation-induced emission (AIE) effect of D-penicillamine capped copper nanoparticles (DPA-CuNPs). The fluorescent DPA-CuNPs were synthesized by a onepot method using D-penicillamine as both reducing agent and stabilizing ligand. The size, morphology and physical chemical properties of DPA-CuNPs were examined by transmission electron microscopy (TEM), fluorescence spectroscopy, fourier transform infrared spectroscopy (FTIR) and absorption spectroscopy. The DPA-CuNPs exhibit AIE effect and show intense red fluorescence (650 nm). In the presence of histamine, DPA-CuNPs are dispersed into small homogeneous particles, causing fluorescence quenching. Based on this reaction, a histamine sensor is constructed. The fluorescence of the CuNPs solution has a good linear relationship with histamine concentration in the range 0.05 μM to 5 μM and the determination limit (3σ/slope) is 30 nM. The estimated method was successfully applied to the determination of histamine in fish, pork and red wine. Keywords Luminescent materials . Histamine detection . Fluorescence signaling .

Introduction Metal nanomaterials show unique size effects. They have been widely applied to biomedical effects [1], photoelectrochemical immunosensor [2], chemical sensor [3], food production [4], clinical diagnosis [5] and have great potential applications in other fields [6]. Physical and chemical properties of copper nanoparticles (CuNPs) are mainly dictated by the size, shape and surface chemistry. Functional groups, such as the thiol group [7], amino group [8] and carboxyl group [9], played significant roles in the synthesis process of CuNPs, as reducing agents or Electronic supplementary material The online version of this article (https://doi.org/10.1007/s00604-020-04271-1) contains supplementary material, which is available to authorized users. * Hong-Bo Song [email protected] * Yi-Wei Wang [email protected] 1

stabilizing ligands. L-cysteine [10], glutathione [11], deoxyribonucleic acid [12] and D-penicillamine [13] are common stabilizing ligands. Some CuNPs synthesis strategies are complicated. Therefore, it is necessary to explore new strategies for the synthesis of stable and intensely fluorescent CuNPs. Biogenic amines (BAs) are low molecular weight compounds containing amino group. BAs are derived from the decarboxylation of their precursor am
