Large Scale Synthesis of Carbon Dots and Their Applications: A Review

Molecules, Год журнала: 2025, Номер 30(4), С. 774 - 774

Опубликована: Фев. 7, 2025

Carbon dots (CDs), a versatile class of fluorescent carbon-based nanomaterials, have attracted widespread attention due to their exceptional optical properties, biocompatibility, and cost-effectiveness. Their applications span biomedicine, optoelectronics, smart food packaging, yet large-scale synthesis remains significant challenge. This review categorizes methods into liquid-phase (hydrothermal/solvothermal, microwave-assisted, magnetic hyperthermia, aldol condensation polymerization), gas-phase (plasma synthesis), solid-phase (pyrolysis, oxidation/carbonization, ball milling), emerging techniques (microfluidic, ultrasonic, molten-salt). Notably, microwave-assisted solid-state show promise for industrial production scalability efficiency. Despite these advances, challenges persist in optimizing reproducibility, reducing energy consumption, developing purification quality control strategies. Addressing issues will be critical transitioning CDs from laboratory research real-world applications.

Leveraging Non‐Radiative Transitions in Asphaltenes‐Derived Carbon Dots for Cancer Photothermal Therapy

Small, Год журнала: 2024, Номер unknown

Опубликована: Авг. 29, 2024

Cancer photothermal therapy leverages the capability of agents to convert light heat for cancer cell ablation and necrosis. However, most conventional (Au, CuS, Pd, mesoporous silica nanoparticles, indocyanine green dye) either face scalability challenges or photobleached upon prolonged irradiation which jeopardizes practical applications. Here, asphaltenes-derived carbon dots (ACDs, 5 nm) are rationally engineered as a low-cost photostable agent with negligible in vivo cytotoxicity. The abundant water-solvating functional groups on ACDs surface endows them excellent water re-dispersibility that outperforms those commercial nanomaterials. Photothermal therapeutic property is mechanistically described by non-radiative transitions excited electrons at 808 nm via internal conversions vibrational relaxations. Consequently, offer mice within 15 days post-exposure one-time near infrared irradiation. This pioneering study showcases first utilization asphaltenes-based materials expected arouse further such various theranostics.

Fe-doped asphaltenes carbon dots for tumor magnetic resonance imaging

Physics of Fluids, Год журнала: 2025, Номер 37(4)

Опубликована: Апрель 1, 2025

Iron-based contrast agents have recently garnered attention as positive (T1) magnetic resonance imaging (MRI) providing an alternative to gadolinium-based mired with the nephrogenic systemic fibrosis downsides. Whereas cores of iron enable T1 MRI enhancement, non-magnetic materials (e.g., polymers) usually deployed stabilize metal affect bulk water diffusion centers. We present innovative approach in designing biocompatible complex asphaltene-derived carbon dots (ACDs) (ACD-Fe), where ACDs enhanced hydrophilicity improves accessibility Fe3+ centers molecules achieve effective tumor MRI. The ACD-Fe design strategy involves synthesizing at a lower temperature (80 °C) high mass yield, followed by doping via easy complexation FeCl3 room temperature. thus serves tissue-tolerant agent (r1 = 1.33 mM−1s−1) for imaging. This report pioneers use and imaging, presenting low-cost, scalable synthesis protocol agent.
