Epigynum auritum-Derived Near-Infrared Carbon Dots for Bioimaging and Antimicrobial Applications

Molecules, Journal Year: 2025, Volume and Issue: 30(2), P. 422 - 422

Published: Jan. 20, 2025

The use of biomass feedstocks for producing high-value-added chemicals is gaining significant attention in the academic community. In this study, near-infrared carbon dots (NIR-CDs) with antimicrobial and bioimaging functions were prepared from Epigynum auritum branches leaves using a novel green synthesis approach. spectral properties synthesized NIR-CDs characterized by ultraviolet–visible (UV-Vis) absorption fluorescence spectroscopy. crystal structures further high-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR), nuclear magnetic resonance (NMR), diffraction (XRD). exhibited minimal toxicity, excellent biocompatibility, high penetrability both vivo vitro environments, making them ideal luminescent probes applications. Moreover, activity was tested against Staphylococcus aureus (S. aureus) Escherichia coli (E. coli), showing bacterial growth inhibition. effect likely attributed to disrupting cell membrane integrity, leading leakage intracellular contents. Therefore, hold promise as fluorescent agents.

Mitigating ammonia inhibition in anaerobic digestion with lignin-based carbon materials synthesized by hydrothermal carbonization

Carbon Research, Journal Year: 2025, Volume and Issue: 4(1)

Published: Feb. 4, 2025

Abstract Ammonia inhibition poses a significant challenge to the efficient and stable operation of anaerobic digestion (AD) systems by leading volatile fatty acid conversion reduced methane production. This study explores utilization lignin-based hydrochar (LHC) carbon quantum dots (CQDs) produced via hydrothermal carbonization alkali lignin alleviate ammonia in AD processes. The results showed that both LHC CQDs help counter decline yield production rate typically associated with inhibition. Notably, addition 1 g/L significantly increased 24.25% compared control group. While limited adsorption, its primary impact was enhancing direct interspecies electron transfer (DIET) through improved redox capacity promoting humic acid-like organics formation. In contrast, charge resistance, system capacity. Optimizing temperature 250 °C further optimized properties, boosting 30.53% at concentration 3 g/L. Microbial community metabolic pathway analyses indicated enriched hydrolytic acidifying bacteria, as well DIET-associated microorganisms, facilitating conversion. process enabled sustained acetoclastic hydrogenotrophic methanogenic pathways, effectively mitigating adverse effects high nitrogen concentrations.
