“…Furthermore, various GQDs synthesis techniques based on industrial waste materials are continually being reported. Examples include electrochemical exfoliation utilizing discarded batteries (figure 3(C)) [99] or the microwave-driven depolymerization of Styrofoam to synthesize GQDs [100]. At the same time, numerous tries for practically applying GQDs synthesized through these methods across various domains are ongoing [101][102][103].…”

A new type of 0-dimensional carbon-based materials called graphene quantum dots (GQDs) is gaining significant attention as a non-toxic and eco-friendly nanomaterial. GQDs are nanomaterials composed of sp2 hybridized carbon domains and functional groups, with their lateral size less than 10 nm. The unique and exceptional physical, chemical, and optical properties arising from the combination of graphene structure and quantum confinement effect due to their nano-size make GQDs more intriguing than other nanomaterials. Particularly, the low toxicity and high solubility derived from the carbon core and abundant edge functional groups offer significant advantages for the application of GQDs in the biomedical field. In this review, we summarize various synthetic methods for preparing GQDs and important factors influencing the physical, chemical, optical, and biological properties of GQDs. Furthermore, the recent application of GQDs in the biomedical field, including biosensor, bioimaging, drug delivery, and therapeutics are discussed. Through this, we provide a brief insight on the tremendous potential of GQDs in biomedical applications and the challenges that need to be overcome in the future.

In this study, the reuse of Citrus fortunella (CF) plant waste, an agricultural product, was evaluated within the scope of sustainability. In this context, selenium nanoparticles (CF‐Se NPs) were synthesized from CF waste extracts and crystal violet (CV) dye was removed. The characteristic structure of the synthesized CF‐Se NPs was determined by X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X‐ray (EDX), Fourier transform infrared spectroscopy (FTIR), UV–vis spectroscopy, and point of zero charge (pHpzc). Batch adsorption tests were applied to determine the effect of the synthesized CF‐Se NPs on CV removal. Four different kinetic and isotherm models were examined using error analysis functions. While the particle size of CF‐Se NPs was determined as 27.58 nm, the pHpzc value was calculated as 9.40, the average surface charge distribution was −24.1 mV, and mass losses were 9.03% and 13.42% at 334.99 and 739.21°C, respectively. The most suitable kinetic and isotherm model for CV removal with CF‐Se NPs was determined to be pseudo‐second‐order with a R2‐value of 0.999 and Freundlich with R2‐value of 0.993, and the qmax was calculated as 23.55 mgCV/gCF‐SeNPs. The effectiveness of CF‐Se NPs synthesized from waste in CV removal is a remarkable issue in terms of sustainable production.
