The 3-aminophthalic acid anion is a light emitter in luminol chemiluminescence. In the present study, the chemiluminescence of the 3-aminophthalic acid anion itself in the presence of hydrogen peroxide-cobalt (II) was studied. The results indicated that 3-aminophthalic acid anion is highly chemiluminescent in the typical hydrogen peroxide-cobalt (II) system. The peak wavelength of this chemiluminescence and the kinetic profile of the 3-aminophthalic acid anion-hydrogen peroxide-cobalt (II) reaction showed similarity with that of luminol, but the chemiluminescence of 3-aminophthalic acid anion had a much lower background signal. In addition, the chemiluminescence mechanism of 3-aminophthalic acid anion-hydrogen peroxidecobalt (II) was also discussed and speculated as the interaction between 3-aminophthalic acid anion and singlet oxygen.

“…Similarly, polystyrene nanoparticles stained with squaraine catenane endoperoxide dyes, which are concurrently chemiluminescent and fluorescent, displayed significantly higher CL than fluorescence, which helped in the imaging of distribution of nanoparticles in mice (Lee et al, 2013). Similar to colloidal and inorganic NPs, enhancement to CL has been investigated with the help of quantum dots (QDs), including both metallic (Song et al, 2019) and non-metallic (Wang D. M. et al, 2019) QDs. Subsequently, enhancement effects such as chemiluminescence resonance energy transfer (CRET) has been discovered (Yao et al, 2017).…”

Tissue imaging has emerged as an important aspect of theragnosis. It is essential not only to evaluate the degree of the disease and thus provide appropriate treatments, but also to monitor the delivery of administered drugs and the subsequent recovery of target tissues. Several techniques including magnetic resonance imaging (MRI), computational tomography (CT), acoustic tomography (AT), biofluorescence (BF) and chemiluminescence (CL), have been developed to reconstruct three-dimensional images of tissues. While imaging has been achieved with adequate spatial resolution for shallow depths, challenges still remain for imaging deep tissues. Energy loss is usually observed when using a magnetic field or traditional ultrasound (US), which leads to a need for more powerful energy input. This may subsequently result in tissue damage. CT requires exposure to radiation and a high dose of contrast agent to be administered for imaging. The BF technique, meanwhile, is affected by strong scattering of light and autofluorescence of tissues. The CL is a more selective and sensitive method as stable luminophores are produced from physiochemical reactions, e.g. with reactive oxygen species. Development of near infrared-emitting luminophores also bring potential for application of CL in deep tissues and whole animal studies. However, traditional CL imaging requires an enhancer to increase the intensity of low-level light emissions, while reducing the scattering of emitted light through turbid tissue environment. There has been interest in the use of focused ultrasound (FUS), which can allow acoustic waves to propagate within tissues and modulate chemiluminescence signals. While light scattering is decreased, the spatial resolution is increased with the assistance of US. In this review, chemiluminescence detection in deep tissues with assistance of FUS will be highlighted to discuss its potential in deep tissue imaging.

“…The significant property of C‐dots is its strong photoluminescence, which was ascribed to surface functionalization and/or their size [21,22] . Compared with other fluorescent nanomaterials, including noble metal nanoclusters (NCs) and semiconductor quantum dots (QDs), C‐dots have aroused increased interest due to their tuneable emission spectrum, superior photostability, low cytotoxicity, good water solubility, excellent biocompatibility, and cost‐effective preparation [23–27] . These merits make them ideal nanomaterials for widespread application in bioimaging, biosensing and chemical sensing, as fluorescent inks, in drug delivery, for photocatalysis, and others [28–30] .…”

A novel and sensitive fluorescence analysis platform was constructed for the detection of chlorogenic acid (CGA) using carbon dots (C-dots) with prominent sensitivity and selectivity. Excitation-dependent emission fluorescence C-dots were fabricated using citric acid and L-histidine as precursors through an efficient one-step hydrothermal treatment. The maximum excitation and emission wavelength of the as-synthesized C-dots were 340 nm and 414 nm, respectively. Moreover, the asprepared C-dots displayed excellent water solubility and good photostability. The fluorescence quantum yield of the as-prepared C-dots was measured to be about 22% using quinine sulfate as the reference. Furthermore, the obtained C-dots were applied to the detection of CGA accompanied with a wide linear range from 1.53 μmol L −1 to 80.0 μmol L −1 as well as a limit detection of 0.46 μmol L −1. More importantly, the proposed fluorescence method was successfully used to analyse CGA in coffee and honeysuckle.
