“…Among natural polymers, gelatin due to its good pharmacological characteristics (as excellent biocompatibility and degradability to non-toxic products) and low cost, could be an excellent candidate for the synthesis of CDs [14,15]. Commonly techniques have been used to synthesis CDs to include electrochemical synthesis [16,17], chemical oxidation [18], laser ablation of graphite [19], ultrasonic methods [20], hydrothermal [21,22], solvothermal [23] and microwave-assisted pyrolysis [24,25]. However, most of these techniques may involve a) complex reactions, b) time-consuming processes, c) post-treatment procedures and d) an expensive carbon source, which limit the applications of CDs.…”

A green and simple process for preparing the polyethylene glycol passivated fluorescent carbon dots (CDs-PEG) have been studied by a microwave pyrolysis method, using gelatin and PEG as starting materials. This method is very effective for development of carbon-based quantum dots from gelatin with high quantum yield (QY). The synthesized CDs-PEG were found to emit blue photoluminescence (PL) with a maximum QY of 34%. At the following research, we investigated the effect of the presence of PEG on PL intensity, and the result showed that CDs-PEG becomes stronger PL properties than pure CDs from gelatin. The synthesized CDs-PEG were characterized by FTIR, TEM, UV-vis, PL, zeta potential and XRD analyses. The anticancer performance of developed CDs-PEG was evaluated by in vitro tests such as MTT assay and fluorescence microscopy analyses. The examination of CDs-PEG as an anticancer drug nanocarrier for methotrexate (MTX) illustrated a better antitumor efficacy than free MTX due to its enhanced nuclear delivery in vitro, which resulting in highly effective tumour growth inhibition and improving targeted cancer therapy in clinical medicine.

We report a facile method by which to synthesize Au/Cdot nanohybrids using carbon dots (Cdots) obtained from rice straw as a direct reducing agent as well as a stabilizer. Rice-straw-derived Cdots possess oxygen-containing functional groups that act as an electron-donating source to reduce Au3+ to Au0 without the use of chemical reagents for the reduction of Au precursors. Additionally, the strong Au-carbon interaction promotes a high electron transfer of the Au/Cdot nanohybrid electrocatalyst, resulting in enhanced performance of the hydrogen evolution reaction (HER). The overpotential is 150 mV at a current density of 10 mA·cm−2 and the TOF value is 0.06·s−1, representing the most outstanding HER performance among Au-based catalysts as a non-Pt HER electrocatalyst. The HER activity is stably maintained for 2000 cycles as well as for 48 h. The synthesis of Cdots, the hybridization of Au/Cdot electrocatalyst, and the production of clean hydrogen fuel using Au/Cdots are zero CO2 emission strategies, not only preventing the emission of pollutants but also satisfying the energy needs of humankind.

Recent years have witnessed a surge in research on aqueous zinc‐ion batteries (AZIBs) due to their low cost, stability, and exceptional electrochemical performance, among other advantages. However, practical manufacturing and deployment of AZIBs have been hindered by challenges such as low energy density, significant precipitation‐related side reactions, slow ion migration, and dendritic growth. Addressing these issues and enhancing the practical application of AZIBs necessitates the development of novel materials. Carbon dots (CDs), with their distinctive structure and superior electrochemical properties, represent an innovative class of carbon‐based materials with broad potential applications for optimizing AZIBs' performance. This study offers a comprehensive review of how CDs can address the aforementioned challenges of AZIBs. It begins with an overview of AZIBs composition and mechanism before delving into the classification, preparation techniques, and functionalization strategies of CDs. The review also thoroughly summarizes the sophisticated roles of CDs as modifiers in electrolytes and electrodes, both positive and negative, and briefly discusses their potential application in membranes. Additionally, it provides a summary of current issues and difficulties encountered in utilizing CDs in AZIBs. This review aims to provide insights and guidance for designing and manufacturing the next generation of high‐performance AZIBs.
