Carbon and graphene-based quantum dots have recently emerged as highly valuable and widely applicable materials based on their low particle sizes (1−10 nm). The incorporated oxygen, nitrogen, and carbon functional groups can significantly enhance the binding capabilities of these materials to various surfaces. In this study, lupine seeds were employed to produce a sustainable and novel material known as lupine carbon quantum dots (LCQDs), by using a straightforward and green microwave hydrothermal reaction. The assembled LCQD material was characterized by several instrumentations such as FTIR, TEM, EDX, XRD, UV−vis, and XPS to confirm the various incorporated functionalities, morphology/particle size, elemental composition, amorphous structure, transition types, and various bonds, respectively. LCQD material was explored to investigate and assess the corrosion prevention performance by various approaches via electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and mass loss techniques. The prepared LCQDs reflected an 89.3% maximum inhibitory effectiveness for carbon steel corrosion upon using 175 mg/L LCQDs in a 1.0 M HCl environment at 40 °C. The EDX, XRD, and XPS techniques were used to confirm the effectiveness of LCQDs in protection of the carbon steel surface and discuss the corrosion inhibition mechanism. The LCQD adsorption mechanism onto carbon steel was also explored by Langmuir and Flory−Huggins isotherms, besides the kinetic−thermodynamic model, to fit the outcomes from the experimental data. The findings revealed that these models were applicable, giving ΔG o ads of −31 kJ/mol, while the adsorption mechanism was correlated to a physical/chemical process. Finally, the outcomes of this study refer to the potential capability of LCQD materials as sustainable corrosion inhibitors without any additional modification via doping or modification with other chemical compounds or materials.

“…Molaei et al synthesized calcium and aluminum-based layered double hydroxide nanosheets, coated them in situ with PEG, then attached CQDs and folic acid. The composite was then loaded with doxorubicin hydrochloride and the release of the drug was found to be pH-sensitive(Molaei, 2023). Ostovar et al synthesized a nanocomposite from gelatin, chitosan, and CQDs to study the loading and release characteristics of the anticancer drug, curcumin.…”

The carbon‐based nanostructures have led to the development of theranostic nanoplatforms for simultaneous diagnosis and therapy due to their effective cell membrane‐penetration ability, low degree of cytotoxicity, excellent pore volume, substantial chemical stability, and reactive surface. In the last few years, extensive efforts were made to design multifunctional nanoplatform strategies based on carbon nanostructures, involving multimodal imaging, controlled drug release capabilities, sensing in vitro, efficient drug loading capacity, and therapy. Carbon and graphene quantum dots (CQDs and GQDs) were the recent entrants, contingently being assessed for drug delivery and bioimaging. With the advancements, these quantum dots have ignited remarkable research interest and are now widely evaluated for diagnosis, bioimaging, sensing, and drug delivery applications. The last decade has witnessed their remarkable electrical, optical, and biocompatible properties since their inception. It is presumed that both of them have high potential as drug carriers and would serve as the next generation of approaches to address numerous unresolved therapeutic challenges. This review examined the recent advances of CQD and GQD based drug delivery applications, challenges, and future perspectives to pave the way for further studies in the future.
