Synthesis and Characterization of Lignocellulose-Based Carbon Quantum Dots (CQDs) and Their Antimicrobial and Antioxidant Functionalities

Molecules, Journal Year: 2025, Volume and Issue: 30(3), P. 667 - 667

Published: Feb. 3, 2025

Carbon quantum dots (CQDs) have recently drawn enormous attention due to not only their unique chemical, biological, and optical properties but also because a variety of renewable biomasses are readily utilized as carbon sources in synthesis. This study investigated the synthesis, characterization, functional evaluation CQDs from unbleached mechanical pulp natural lignocellulosic resource. The were synthesized using one-step hydrothermal synthesis with varying temperature, time, consistency. resulting exhibit spherical shape size distribution 9.73 ± 0.82 nm lattice parameters 0.21 0.34 nm, indicating graphite core. photoluminescence spectra showed evident fluorescence characteristics, an emission peak at 435 excitation wavelength 370 nm. as-prepared chemically composed C=C C=O bonds linked hydroxyl carboxyl groups, which typically found lignocellulose-based CQDs. demonstrated antibacterial activity exceeding 99.9% against E. coli lowest concentration 0.75 mg/mL. Demonstrating its antioxidation property, DPPH radical scavenging surpassed 90% more than 40 µg/mL CQD solution.
