Abstract
Carbon dots (CDs) are a recent addition to the nanocarbon family, encompassing both crystalline and amorphous phases. They have sparked significant research interest due to their unique electrical and optical properties, remarkable biocompatibility, outstanding mechanical characteristics, customizable surface chemistry, and negligible cytotoxicity. Their current applications are mainly limited to flexible photonic and biomedical devices, but they have also garnered attention for their potential use in intelligent packaging. The conversion of food waste into CDs further contributes to the concept of the circular economy. It provides a comprehensive overview of emerging green technologies, energy-saving reactions, and cost-effective starting materials involved in the synthesis of CDs. It also highlights the unique properties of biomass-derived CDs, focusing on their structural performance, cellular toxicity, and functional characteristics. The application of CDs in the food industry, including food packaging, is summarized in a concise manner. This paper sheds light on the current challenges and prospects of utilizing CDs in the packaging industry. It aims to provide researchers with a roadmap to tailor the properties of CDs to suit specific applications in the food industry, particularly in food packaging.

Abstract
Phytochemicals have the potential to treat resistant cancer. They are delivered to the target site via nano-based carriers. Promising results are seen in preclinical and in vitro models, as phytochemical-based nanoformulations have improved cell cytotoxicity compared to single agents. They can synergistically inhibit cancer cell growth through p53 apoptosis in MCF-7 breast cancer cell lines. Moreover, synergic viability in reproducible glioma models at half inhibitory concentrations has been shown. Through caspase activation, phytochemical-based nanoformulations also increase cell death in 4T1 breast cancer cell lines. They have shown improved cytotoxicity at half inhibitory concentrations compared to single-agent drugs in cervical cancer. In terms of colorectal cancer, they have the potential to arrest cells in the S phase of the cell cycle and synergistically inhibit cell proliferation. In squamous cell carcinoma of the tongue, they inhibit protein kinase B (Akt)/mammalian target of rapamycin (mTOR) pathways. This review reports on developments in the therapeutic management of various cancers using phytochemical-based nanoformulations, which have shown potential benefits in the clinical management of cancer patients, halting/slowing the progression of the disease and ameliorating chemotherapy-induced toxicities.

Abstract
Introduction Nowadays, in nanotechnology and material science, biosynthesis of the metal nanoparticle is a promising approach. Methods In the current research, the extract of the Korean Ueong dry root (BdkR), which belongs to the Asteraceae family, was used as a reducing and capping agent, for the green synthesis of the BdkR-Ag nanoparticles in a cost-effective and highly efficient manner. In this study for the reaction measures, UV-Vis spectroscopy was applied. SEM, EDX, FTIR, XRD, mean size distribution, and zeta potential were used for the characterization of the green synthesized BdkR-AgNPs. In the beginning, the primary phytochemical screening of BdkR extract was estimated and the cytotoxicity, antidiabetic, antioxidant, and antibacterial activities of the green synthesized BdkR-AgNPs were evaluated. Results According to the results, the BdkR extract is rich in various phytochemicals and the generated AgNPs were crystalline in nature. The surface plasmon resonance value of the BdkR-AgNPs was 444 nm confirming the synthesis of AgNPs. The BdkR-AgNPs displayed four clear diffraction peaks at 2 theta angles (38.22); (46.15); (64.88); (76.83), respectively, which are equivalent to (111), (200), (220) and (311). The obtained nanoparticles have a zeta potential of -17.0 mV. Furthermore, the generated BdkR-AgNPs exhibited considerable antidiabetic effect in terms of the inhibition of α-glucosidase with a maximum inhibition value of 95.41% at 5.0 µg/mL and more than 86% inhibition at 2.5 µg/mL and the estimated IC50 value was found to be 0.653 µg/mL. Further, it also displayed a significant cytotoxicity activity against the HepG2 cancer cell lines at 10 µg/mL and 100 µg/mL concentrations with 86% and 88% of inhibition, respectively. Besides this, the synthesized AgNPs also displayed promising antioxidant activities in terms of the DPPH (IC50 value - 56.26 µg/mL), ABTS (IC50 value - 171.43 µg/mL) and reducing power (IC0.5 value - 227.42 µg/mL). Discussion The multipotential effects of the synthesized BdkR-AgNPs might be attributed to the presence of the bioactive compounds in the BdkR extract that acted as the capping and reducing agent in the synthesis process. The green synthesized BdkR-AgNPs exhibited promising bioactive potential for their future applications in the food and biomedical field.

Abstract
Plant secondary metabolites such as flavonoids demonstrate high degrees of antioxidant, anti-inflammatory, and anticancer activities. Among flavonoids, quercetin plays an important role in inflammation by downregulating the level of various cytokines. Thereby, in this work, onion (Allium cepa) peel was successfully utilized for the synthesis of gold nano-bioconjugates acting as a natural therapeutic drug. In this process, crude onion peel extract was first divided into different fractionates, namely, ethyl acetate, butanol, methanol, and water, and they were subjected to various preliminary studies of antioxidant activities. The ethyl acetate fractionate shows high antioxidant activities in all the assays. The bioactive components were identified and found to contain a high amount of quercetin as confirmed by liquid chromatography with tandem mass spectrometry and high-performance liquid chromatogrpahy. Three gold nano-bioconjugates were prepared with different concentrations of the ethyl acetate fractionate. Various biochemical anti-inflammatory assays were carried out and compared with the active ethyl acetate fraction of the onion peel drug (OPD). The cytotoxicity of the nano-bioconjugate system and the OPD was checked in the myoblast L6 cell line from skeletal muscle tissues to evaluate the toxicity. All the three nano-bioconjugates A, B, and E demonstrated high percentages of cell viability, viz., 73.07, 72.3, and 69.15%, respectively, at their highest concentration of 200 μg/mL. The OPD also showed 88.56% cell viability with no toxic effects in the myoblast L6 cell line from skeletal muscle tissues. The reactive oxygen species reduction of nano-bioconjugate B showed a marked reduction of 76.77% at a maximum concentration of 200 μg/mL, whereas the OPD showed 68.17%. Hence, through this work, a cheap source of nano-bioconjugates is developed, which can act as a potent antioxidant and anti-inflammatory agent and are more active in comparison to the OPD alone.
