Black Phosphorus Quantum Dots with Exposed (113) Planes on Chemiluminescent Luminol–K3Fe(CN)6 for Detection of Dopamine

“…39−41 It was found in our previous work that the catalytic effect of BPQDs can significantly boost lucigenin CL, suggesting that BPQDs are promising nanomaterials for CL research. 42 Nonetheless, most of the current CL systems still require an alkaline environment to achieve high-quality CL performance. 40,43−46 It should be noted that the strong alkaline conditions lead to a low signal/noise ratio and poor universality of the systems.…”

“…Among various QDs, metal-free QDs, especially those of pure elements, have attracted widespread research attention because of their low toxicity and excellent properties. Black phosphorus quantum dots (BPQDs) exhibit extraordinary catalytic potential by virtue of their superb electronic conductivity and abundant active sites, , which have been applied in numerous fields. − Many investigations have indicated that the participation of BPQDs in the CL system has provided new avenues to promote the CL emission and expand the application range. − It was found in our previous work that the catalytic effect of BPQDs can significantly boost lucigenin CL, suggesting that BPQDs are promising nanomaterials for CL research .

Chemiluminescence of lucigenin-tetracycline and itsapplication for sensitive determination of procyanidin

“…Chemiluminescence (CL) has been considered as a popular and powerful analytical technique and universally used in chemical and biological sensing fields owing to its simple and relatively cheap instrumentation, quick response, high sensitivity, wide linear range and low background noise [ 1 , 2 ]. Lucigenin ( N, N ′-dimethyl biacridinium dinitrate), one of the most extensively used chemiluminescent materials, has gained enormous concern due to its excellent CL properties and broad range of analytical applications, including drug analysis, metal ion detection, clinical diagnosis [ 3 – 5 ]. Hydrogen peroxide as a classical co-reactant generates strong CL signals with lucigenin in alkaline medium.…”

“…However, the poor specificity and instability of the traditional lucigenin-H 2 O 2 CL system in the presence of common interferents including metal ions and their complexes result in limitations on its development of sensing analysis [ 6 ]. In recent years, metal nanoparticles or quantum dots (carbon dots and black phosphorus quantum dots) have been utilized as catalysts in lucigenin CL to stimulate the emission reaction [ 3 , 7 – 9 ]. Therefore, it is of great aspiration to explore new lucigenin CL systems to broaden the scope of CL applications.…”
