“…The reason was possibly due to the interaction between the FNs and calcium after the FNs had chelated Ca(II). Similar results were also found in our previous studies [15]. In addition, the aqueous solutions of the FNs and FNs-Ca(II) were colourless and transparent; however, they exhibited blue fluorescence (Figure 1b,c, inset) under the illumination of a 365 nm ultraviolet light, which was consistent with the FNs from other foods [18].…”

“…An FLS 980-spectrofluorometer from Edinburgh Instruments (Edinburgh, UK) was used to measure lifetime with a 320 nm laser as the excitation source. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), and zeta potential analysis were conducted using previously reported methods [15]. The microstructure and local element composition of the FNs and FNs-Ca(II) were characterized by a JSM-7800F scanning electron microscope from JEOL Ltd. (Tokyo, Japan).…”

“…Sun et al described a heptapeptide from the ovum of sea cucumber as a chelating agent for enhanced calcium delivery [14]. Although these peptides have excellent calcium chelating abilities, the process of preparing the peptides is tedious and costly, which makes it difficult to be widely used [15]. Therefore, the development of an innovative calcium carrier with a simple production process, higher stability, and better biocompatibility is highly desirable.…”

Calcium is considered as an important nutrient element for the maintenance of human health, and food-borne nanoparticles (FNs) produced during food processing may have potential as nanocarriers for calcium ion delivery. Beef is an important source of animal protein that has high protein and low fat content and is rich in a variety of amino acids; thus, beef may be a suitable material for the development of calcium nanocarriers. In this paper, FNs were synthesized from beef by one-step hydrothermal synthesis. The FNs had a spherical shape with a size of about 3.0 nm and emitted a bright blue fluorescence under 365 nm ultraviolet irradiation. The amino nitrogen atom and carboxyl oxygen atom of the functional groups on the surface of the FNs were the main binding sites for the chelation of Ca(II). The size of the FNs-Ca(II) complex was about 4.75 nm, and the specific signal peak of calcium at 3.7 keV was observed in its energy dispersive X-ray spectroscopy spectrum. The viability of cells treated with FNs-Ca(II) was more than 65%, while viability was only 60% after treatment with CaCl2. The results showed that the FNs from beef have great potential in calcium delivery for the development of a calcium supplement.

“…28 The fluorescence lifetime is connected with the coupled surface energy traps, bandgap, and surface chromophore structure. 35 By fitting the fluorescence decay curve with the two-exponential function, the fluorescence lifetime of the onion carbon dots was calculated to be 4.45 ns (Fig. S7b†).…”

“…Many works have been conducted in understanding the potential risks of foodborne NPs, but little information is available about their subacute and chronic toxicity for foodborne hollow nanostructure like OCNPs. These foodborne NPs may be used as nanocarriers in the delivery of metal ions, including Zn 2+ , Ca 2+ , Fe 2+ , and so on, due to their small size and good water solubility [ 17 , 18 , 19 ]. The bioeffect of OCNPs is barely studied and their toxicity is probably highly related to their structures, including size and morphology [ 20 ].…”

Although the presence of foodborne nanoparticles was confirmed in grilled fish in a previous study, the evaluation of potential health risks of these NPs was insufficient. In the present study, the potential toxicity of onion-like carbon nanoparticles (OCNPs) separated from grilled turbot Scophthalmus maximus L. was evaluated using mouse osteoblasts cells model and zebrafish (Danio rerio) model. Cytotoxicity evaluation revealed that the OCNPs penetrated into the MC3T3-E1 cells without arousing cell morphology changes. No evident apoptosis or damage of cells was observed with increasing OCNPs’ concentration to 20 mg/mL. In the hemolysis test, OCNPs did not show an obvious hemolysis effect on red blood cells. In the acute toxicity test, the LC50 value (212.431 mg/L) of OCNPs to zebrafish showed a weak acute toxicity. In subacute toxicity test, after exposure to OCNPs (30 mg/L, 40 mg/L) for 10 days, a significant increase of reactive oxygen species level of zebrafish was observed. Meanwhile, redundant ROS content caused inhibition to several antioxidant enzymes and induced lipid and protein peroxidation damages according to the upregulation of malondialdehyde and protein carbonyl levels. The chronic toxicity test results indicated that oxidative stress was only observed in the high concentration group of OCNPs-treated zebrafish.
