Published: Feb. 1, 2025

Abstract The development of biomass‐derived nanomaterials like carbon nanotubes (CNT), graphene, and nanofibers has revolutionized multiple domains in the scientific industrial communities. Notably, quantum dots (QDs), such as (CQDs) synthesized from biomass, have garnered significant attention for their synthesis biomass sources, marking a shift toward sustainability eco‐friendliness. Quantum (QDs) are 0D type nanoparticles whose properties typically depend on shape, size, materials used synthesis. This review outlines top–down bottom–up approaches CQD production lignocellulosic algal sources. It also discusses various characterization techniques focusing optical structural properties. Furthermore, article elaborates applications CQDs, catalysis, supercapacitors, drug delivery. provides comprehensive overview synthesis, characterization, versatile utility using green sustainable source material. is to be noted that CQDs demonstrate characteristics comparable or superior those metal‐based semiconductor dots, organically CQDs.

Recycling Motorcycle Exhaust Soot into Fluorescent Graphene Oxide Quantum Dots for Sensing Ferrocyanide Ions and Bioimaging Cells: A Method for Waste Utilization

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: March 31, 2025

Graphene oxide quantum dots (GOQDs) with a high yield (50%) were synthesized using soot collected from motorcycle (petroleum vehicle) exhaust pipe and applied as sensors for ferrocyanide ([Fe(CN)6]4–) ions bioimaging agents in cancer cell line. X-ray photoelectron spectroscopy (XPS) data the GOQDs revealed C/O ratio of 2.49, which was close to that graphene (GO). The exhibited strong blue fluorescence. High sensitivity detect [Fe(CN)6]4– reported detection limit 0.46 nmol mL–1, linear relationship achieved concentration range 100–1100 μg L–1. results demonstrate utility detecting real scenario. almost negligible cytotoxicity cells internalized within 4 h incubation, emitting fluorescence cytoplasm. This suggests are promising biomedical applications. In general, these waste-derived appear be good chemo- biosensing probes real-life

Carbon dots as smart biosensing and imaging materials delving with antimicrobial, antifungal, and antiviral potentials against infectious pathogens

Journal of the Chinese Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 12, 2025

Abstract In the emerging era of infectious diseases, antimicrobials are widely applied against pathogenic microbes (i.e., bacteria, fungus, or virus) to avoid global mortality. Nonetheless, quite a few microbiome adopted genetic mutations over extended period and fostered sustainable resistance towards existing newer antibiotics. Carbon dots (CDs) carbon‐based nanomaterials, unveiled their potential as antifungal, antibacterial, antiviral agents resembled with ease synthesis, reduced toxicity, smart functionalization, high aqueous dispersibility, auspicious biocompatibility. This review has emphasized discussion corroborated types CDs numerous properties tailored biofunctionalization. Further article was featured antiviral, bioimaging, biosensing, anticancer responsiveness (in vivo in vitro mode) followed by biocompatibility, toxicity assessments, challenges, future prospectives.
