The potentials of biomass-based carbon quantum dot (CQD) as an adsorbent for batch adsorption dyes and its photocatalytic degradation capacity which are congo red (CR) methylene blue (MB) have been conducted in this study. CQDs properties, performance, behaviour, photoluminescence characteristics were assessed using experiments carried out under operating conditions including, temperature, pH dosage. morphological analysis revealed that highly porous, uniform, closely aligned multi-layered. presence hydroxyl, carboxyl carbonyl functional groups indicated the significance oxygenated groups. Spectral confirmed their photoluminescent quality by exhibiting high excitation intensity possessing greenish-blue fluorescence UV radiation. removal percentage adsorbed both CR MB was 77% 75%. Langmuir isotherm pseudo-second-order models fitted results. Thermodynamics process exothermic spontaneous, with excellent reusability stability. efficiency on more than 90% sunlight irradiation obeyed first-order kinetic model. These results demonstrated to be outstanding photocatalyst organic dye degradation.

Carbon dots (CDs) are nanostructures containing mainly carbon atoms and abundant functional groups. With remarkable adjustable physicochemical properties, CDs have excellent hydrophilicity, photoluminescence (PL), biocompatibility, low toxicity. Although the numerous advantages make a research target for synthesizing advanced materials, some limitations pertinent must be corrected. Rare earth elements (RE) candidates doping CDs, obtaining hybrid materials called RE-CDs to optimize luminescence applicability, quantum yields. Hybrids allow combination of advantageous characteristics both RE, drastically improving their luminous magneto-optical imaging performance opening door practical technological applications. To date, no studies in literature provided in-depth analyses methods used prepare RE-CDs, characterization techniques used, challenges, critical analysis what could improved synthesis by proposing solutions. fill this gap, review initially presents detailed survey RE separately. Subsequently, addressed, as well obtainment, commonly characterizations, recent applications, from analyte detection functionality medical nanodevices. Finally, criticisms suggestions future work also discussed inspire new discoveries about potential derived RE-CDs.

Carbon dot (CD) nanoparticles offer tremendous advantages as fluorescent probes in bioimaging and biosensing; however, they lack specific affinity for biomolecules, limiting their practical applications selective targeting. Nanoparticles with intrinsic a target have imaging, cytometry, therapeutics, etc. Toward that end, we report the transferrin receptor (CD71) targeting CDs, synthesized first time. The formation of these particles is truly groundbreaking, direct tuning nanoparticle was achieved by simple careful precursor selection protein, which has characteristic interest. We hypothesized retention original protein's peptides on surface provides CDs some function enabling binding to receptor. This confirmed FTIR (Fourier transform infrared) data subsequent affinity-based cell assays. These (Tf)-derived been shown possess an CD71, cancer biomarker ubiquitously expressed nearly every line due its central role mediating uptake cellular iron. were tested using human leukemia HL60 demonstrated CD71 triggering transferrin-mediated endocytosis via clathrin-coated pits. particle characterization results reflect carbon-based bright violet fluorescence 7.9% quantum yield aqueous solution. unpresented proved retain functional properties protein. Indicating this process can be repeated other disease biomarkers ranging from biosensing diagnostic targeted therapeutics.

Abstract Highly luminescent carbon dots (CDs) have garnered significant attention and are increasingly utilized in various fields. Despite its importance, there has been a lack of comprehensive reviews focusing specifically on highly CDs. It is aimed here to fill that gap by exploring CDs with high photoluminescence quantum yield (PLQY), starting an examination the mechanisms underlying The selection synthetic raw materials preparation methods along research progress reviewed information across bands then statistically summarized several tables. Subsequently, structural features, synthesis methods, purification strategies lead PLQY based analyzing collected examples Furthermore, luminescent‐based multifunctional applications bioimaging, light‐emitting diodes, solar concentrators, lasers introduced. Finally, current landscape evaluated, existing challenges identified, feasible directions proposed for future development.
